These are great tips on Grocery Shopping from zenhabit.net. I have found these to be really helpful. Maybe you will too.

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.
