Nearly every grocery store has a discount bin or two. Although it may look like a bunch of junk that you'd never be interested in, you might be surprised what you can find. If you're not afraid of a few dents in your cans, search the bins for canned fruits and vegetables, usually marked more than 50% off. Look for dried foods, like beans and rice, as well. Stock up on the discounted food; it will taste just as good!
