Groupon and Living Social are prime candidates for impulse purchases. They appear in your inbox with something you wanted already, and then HOORAY! It’s 70% off. The lure of a deep discount paired with the convenience has led to a lot of bad decisions. If you have your payment information stored in the app, you’re just one tap and a catchy subject line away from a purchase you may never use. Many of the daily deal websites have fine print that is easy to overlook. Maybe you simply purchased and then realized you couldn’t use it up before the expiration. You could sell it off on Lifesta. Or you can use the handy service at Presentify.me to turn your ugly looking voucher number into a snazzy certificate for a loved one. Now you’ll never have to let a coupon go to waste again.
