Whenever a free sample arrives, guess what comes with it? Good guess. Manufacturer coupons, and usually good ones at that. Also, the possibility of receiving coupons and offers by mail is certainly greater now that they have my address on their mailing list. So next time you think "Nah, I'm not interested in a tiny sample tube of peanut butter or shampoo, especially when I have full-size containers at home." Think of it as free special coupons that can turn into extreme savings when you find a good sale, maybe a BOGO, and a store coupon stacked. Don't forget to load your store loyalty cards with eCoupons from Upromise or Saving Star to put some cash in your pocket for shopping.
