Last minute life-saver - updated review
Great idea!  A couple of these were included with a recent order.  I've already used one, and can see keeping them on hand for last-minute gifts.  The ones I got were a generic one and a Christmas design.<br />Update:  I should have said that the flex cards I first received unsolicited were cardstock "stickers" that I peeled off a backing to reveal the serial numbers.  The ones you can order are actual plastic gift cards.  I actually prefer the paper ones - they can be literally stuck inside a greeting card and mailed without the tell-tale hard plastic card.  Too bad - guess I have to go back to emailing gift cards.
