We all know that one person who, in lieu of a present, hands you a voucher and tells you to get yourself something nice. Whatever your feelings on that strategy, it's clear that Amazon wants to be the one-stop shop for that type of gift-giver. That's why the company has quietly launched Surprise! an app that enables you to send seasonal e-cards alongside vouchers for the everything store. For added convenience, you can even link the app to your Facebook timeline, enabling you to send cash-based gifts to loved ones just in time for their birthday in a way that won't make you look like you did it all at the last minute, no sir.
