23. Know about the greatness of competitor coupons.
Say you're about to buy something at Bed, Bath & Beyond but you have a coupon to a competitor to BBB. Show it to the cashier, and they may offer you the same discount. If a retailer accepts competitor coupons, there are usually a few parameters for getting the discount, but it's always worth a try. Lifehacker has a good intro to competitor coupons.

Ever seen an amazing product at retailers like Urban Outfitters or Bloomingdale's, but it's not the store's brand? Retailers tend to acquire different brands and sell them at a higher price for profit. Try going directly to the retailer that makes the product and you might be able to save up to 20%.
