A while ago I had a reward coupon from a retailer that expired. I called them and asked our they would extend it and they did. Then I misplaced the coupon for several months.
Yesterday my wife found the coupon so I went to the website and noticed they were having a sale. Using the coupon and the discounts online I got $20 worth of stuff for the house shipped for free to my house for $0.89! Coupon (that should have been expired) found in the nick of time for a huge sale and fee shipping?! Godincidence!
