12. Compare stores.
Look at prices in several stores, if you have a choice. If you find one store is generally less expensive, stick with it.
13. Compare forms of food.
Buy a lower-cost form of a product if there's no major difference between them. For example, try the day-old bread, if it is to be eaten soon. Also, take time to compare frozen, fresh and canned products.
14. Look down.
Here's a tip you may not have heard of before: Look down while shopping at the grocery store. In many grocery stores, the best bargains are closer to the floor. The pricier items are often at eye level.
15. Skip specialty items grouped together.
Things like chips and dips together can result in impulse buying, according to Quick and Simple magazine. And seeking out the bargain bins can save money, too.
