Here’s buying bulk tips on how to take advantage of discounts without packing on pounds:  • Buying Bulk Tip #1: Stow it away One in three people binges when snacks like nuts or chips are kept in plain sight, Wansink has found. If your cupboard is too full to fit the pretzels you’re eyeing in aisle five, take a pass this time around. • Buying Bulk Tip #2: Divide and conquer Divvy up your tub-o’-granola into smaller containers—Wansink’s research indicates that bigger packages prompt people to gobble up to 42% more than they would from sensible sizes. Use clear plastics so you can quickly survey what’s already on hand before you go shopping.  • Buying Bulk Tip #3: Thumb through your cookbooks Work extra food into planned meals (often, cookbooks include ideas for substitutions). Marked-down veggies can be added to homemade soup, and breakfast bran flakes can fill in for a muffin mix. • Buying Bulk Tip #4: Buddy up Bring a friend to the store with you. You can share great finds that often come in bundled multiples, such as jars of jelly or boxes of pasta. Same discount—half the temptation. More from Prevention: What To Buy Organic—And What To Skip
