For me, Frugal Grocery Shopping essential because I have a large family and groceries are one our biggest expenses.  (in Australia Food is Stupidly Expensive).  I have searched the net looking for money saving tips and advice, so first off let me say that these are not all my tips, they were written by Leo Babauta, who writes at ZenHabits.net

We are all different,  so pick and choose which the tips might work for you. Choose two or three tips which look promising and once those become habits you might want to add a few more.

Frugal Grocery Shopping

1. Always go with a list. If you go without a list, you may as well just throw your money away. Better yet, donate it to me — I probably need it more than you. 🙂 Seriously, though, you need to prepare a list of everything you need, pulling from your weekly menu (next tip) and checking to make sure you don’t have it in your pantry, fridge or freezer. Make sure you’re not forgetting anything. Now stick to that list.
2. Plan out a weekly menu. This is the best way to ensure that your list is complete, and that you have enough to serve your family dinner for the week. I often plan a weekly menu and then duplicate it for the next week — this way I can shop for two weeks at once. Be sure to plan a leftovers night.
3. Don’t go when you’re hungry. This is a common tip, but it’s true: when you’re hungry, you want to buy all kinds of junk. You’ll end up spending a lot more. Eat a good meal first, and you’ll be more likely to stick to your list.
4. Have a budget. When I go to the store, I know exactly how much I can spend. Then I try my best to stick within that limit. If you don’t know how much you can spend, you’ll certainly spend too much.
5. Do a rough running tally. Related to the above tip, if you want to stay within your budget, it’s best to know where you’re at. Then, when you can see you’re going to go above it, you can decide whether you really need that 10-lb. box of bon bons. I keep a running tally on my grocery list, just rounding off so I can do some quick math. An item costs $1.85? I say $2. Then I don’t need a calculator or all those complicated math skills.
6. Keep a list on your fridge, and write things down immediately. When you run out of something, don’t leave it to your memory. Jot it down immediately, and you’ll never have to run back to the store because you don’t have eggs.
7. Make a pantry checklist. Make a checklist of everything you normally stock in your pantry. Keep it posted on the pantry. Put a slash next to each item for the number of items you have (if you have two cans of stewed tomatoes, put two slashes). Then, when you use something, turn the slash into an x. This makes it much easier when it comes time to make your list.
8. Keep things stocked for quick-n-easy meals. Easy meals for us might be spaghetti or mac-n-cheese or a quick stir-fry. We’ve always got the ingredients on hand, so we can whip something up fast when we’re feeling lazy.
9. Buy in bulk when it makes sense. If you can save money, over the course of a month or two, by buying in bulk, plan to do so. But be sure that you’re going to use all of it before it gets bad — it isn’t cheaper to buy in bulk if you don’t use it.
10. Keep your receipts, then enter into a spreadsheet. This will be your price list. Use it so you know when bulk or sale items are a good deal. It’s also a great way to comparison shop between stores — buy your baking goods in Store A but your fresh fruits in Store B. The spreadsheet can also serve as a checklist to use when you’re compiling your shopping list.
11. Buy frozen veggies. While fresh veggies are a little better, frozen veggies are almost as good, and much better than nothing. And since you can keep them in the freezer, they rarely go bad.
12. When you’re running low, write it down. Don’t wait until you run out. when you see there’s only three toilet paper rolls left, put it on your list. Because when you run out, it will be too late. 🙂
13. Cut back on meat. Meat is expensive. We have vegetarian meals several times a week (think pasta or chili) and for other meals, you could just use a little meat as a kind of seasoning instead of the main ingredient — think Asian, Indian and other such cultural food. Actually, I eat vegetarian all the time, but the wife and kids do a little of each.
14. Pack your own lunch snacks. Buying pre-made snacks is convenient, but a big waste of money. Buy little baggies and buy the snacks in bulk, then it will take just a few minutes to pack some snacks for lunch each day.
15. Make leftovers for lunch. Plan to cook a bit extra for each dinner, so that you’ll have leftovers for your lunch and for the kids’ lunches. Pack it right away, after dinner, so you don’t have to worry about it in the morning.
16. Cook a lot, then freeze. Alternatively, you can cook a whole mess of spaghetti (for example) and freeze it for multiple dinners. A great idea is to use one Sunday and cook a week’s (or even a month’s) worth of dinners. Plan 5-6 freezable dinners and cook them all at once.
17. Always have batteries, toilet tissue and light bulbs. And other necessities that you always seem to run out of — buy a whole bunch when they’re on sale, or buy in bulk. Be sure to check to see if you have these items before you go to the store.
18. Try crock pot dinners. We discovered these in the last year, and they are easy and cheap and tasty. Cut up a bunch of ingredients, throw them in the pot in the morning, and have dinner ready for you when you get home. Can anything be more perfect than that? I submit that it cannot.
19. Clip coupons. I know, sometimes they seem like too much trouble. But it’s not really that hard to clip a few coupons and toss them in a coupon envelop to take on your grocery shopping trip. And you can save 10-20% of your bottom line with coupons. Check store entrances, newspaper and flyers for coupons.
20. Only use coupons for items you were already planning to buy. Don’t let them trick you into buying something that’s not on your list, just to “save” money.
21. Look for specials. Every store has specials. Be sure to look for them in the newspaper, or when you get to the store (they often have unadvertised specials — look on the higher and lower shelves for deals). Don’t buy them unless they’re things you always use.
22. Try the store brands. Brand names are often no better than generic, and you’re paying for all the advertising they do to have a brand name. Give the store brand a try, and often you won’t notice a difference. Especially if it’s an ingredient in a dish where you can’t taste the quality of that individual ingredient.
23. Cut back on your “one-item” trips. They waste gas, and almost inevitably, you buy more than that one item. If you plan ahead, make a weekly menu, and shop with a list, this should drastically reduce the number of trips you make for a small number of items. But if you still find yourself running out for a few items, analyze the reason — are you not making a good list, are you forgetting some items from your list? Stock up on the things you frequently go out for.
24. Sugar cereals are a bad buy. Lots of money for no nutrition. Look for whole grain cereals with low sugar. Add fruit for better flavor.
25. Be watchful at the register. Keep an eye on the scanner — you’ll keep the cashier on his toes, and catch any mis-priced items.
26. When there’s a sale, stock up. Sale items can be a great deal. If it’s an item you normally use, buy a bunch of them.
27. Comparison shop. Look at the different brands for a certain type of product, including store brands. Sometimes there will be a significant difference. Be sure you’re comparing apples to apples — you need to divide the price by the amount (ounces, pounds, etc.) in order to get the comparable unit price.
28. Go during slow times. One of my favorite times to shop is late at night. But during working hours or other non-peak times is good too. Avoid right after 5 p.m., on paydays and near major holidays.
29. Know when the store stocks its fresh fruits and veggies. In my area, that makes a big difference. Fruits and veggies can go bad quickly, because they have to be shipped. So I know that the store re-stocks on Thursdays, and so I usually go on Thursdays or Fridays, otherwise I’ll be getting old items.
30. Plan one big trip a month for bulk staples. You can get fresh items at another store on other weeks, but doing a big bulk trip will cut back on the expense and amount you have to carry for the other three weeks. Avoid buying on impulse at the bulk store too — just because they sell a lot of it doesn’t mean you’re saving, if you weren’t planning on buying it in the first place.
31. Avoid trips to the corner store. Or the gas station! These are some of the most expensive stores. (Ranking right up there with airport stores.)
32. Try co-ops. You can often save a lot of money at these types of places for staples.
33. Consider shopping at two stores. There’s no store with a monopoly on savings. Each has savings on different items on different weeks. You might switch between two stores on alternate weeks.
34. Think deep freeze. If you really want to save, you’ll need a big freezer. Ask around — someone you know might have a relatively new model they don’t need anymore. You can use freezers to stock up on meat, frozen veggies, and similar staples, and to freeze big batches of pasta, casseroles, and other dinners you prepare ahead of time.
35. Use everything possible. Got a bunch of leftover ingredients (half an onion, a bit of tomato, some pasta, a few other veggies?) … combine them for a quick meal, so that these don’t go to waste before your next grocery trip. The more you can stretch the food, and the less you waste, the less you’ll spend in the long run.
36. Don’t waste leftovers. Have a list on your fridge of what leftovers are in there, so you don’t forget about them. Plan a leftover night or two, so you’re sure to eat them all. Pack them immediately for lunch, so they’re ready to take the next morning.
37. Don’t buy junk food (or buy as little as possible). Junk food not only costs a lot of money for about zero nutrition, but it makes you and your family fat and kills you. Talk about a bad deal! Opt for fruits and veggies instead.
38. Rain check. If an item is on sale but the store has run out of stock, ask for a rain check.
39. Go when the kids are in school. When you bring kids, they will pester you and pester you until you buy some kind of junk food. Even if you’re able to stick to your guns, it’s not pleasant saying no 10 million times. In most cases, you’ll save money shopping without the kids.
40. Go for whole foods. The processed kind is lacking in nutrition and will make you fat. Look for things in their least processed form — whole grain instead of white or wheat bread, fresh fruit instead of canned or juice, whole grain cereal or oatmeal instead of all other kinds of cereal. You get the idea.
41. Read labels. Look for trans fat, hydrogenated oils, high amounts of sugar, saturated fat, lots of sodium, cholesterol. Then avoid them like the plague. Look instead for fiber, good fats, protein, vitamins, calcium.
42. Clean out your fridge. You’ve got stuff growing in there and turning from solids to liquids. The leftovers have begun to organize their own political party. Toss em out and make room for the new.
43. Stick to your list. Avoid impulse buys. They are almost always bad, and even if it’s just a couple dollars, they will add up to $50-100 for a trip. Over the course of a year, that can mean thousands. Tell yourself you will not buy anything that’s not on your list unless it’s an absolute necessity (why isn’t toilet paper on my darn list?).
44. Use store savings cards. These can add up to big savings over the long run.
45. Cut back on your restaurant eating. It’s never cheaper or more nutritious than eating at home. Plan your dinners (see above tip) and bring your lunches to work and save a ton of money.
46. Avoid frozen dinners or prepared entrees. Again, these cost way more and are usually much less nutritious.
47. Drink water. If you regularly drink iced tea, Tang, sodas or other types of drinks, cut those out completely and just drink water. It’s much better for you, and much cheaper.
48. Prepare your grocery list by aisle. If you regularly shop at the same stores, organize your list so that you can easily find and check off items as you walk down the aisle. We always shop from right to left, so we’re not constantly running back and forth in the store.
49. Get cloth grocery bags. You’ll save tons of plastic over time, and help the environment tremendously.
50. Pack healthy snacks for the kids. Whole wheat crackers, popcorn, cut-up fruit, raisins, and other kid-friendly snacks are much better than the junk you often see in kids’ lunches. And cheaper.
