American Express Gold Butterfly Card

Credit cards are a necessary evil of life these days, so if you're going to carry one, you might as well make it as stylish as possible. The new American Express Gold Butterfly Card (free with Gold Card membership) is a companion card to your current Gold Card that folds into a tiny case with a clip on the back. The Butterfly card will have a different number than the Gold Card account it's linked to, but all the charges end up on the linked account — the Butterfly has a unique number so that you can more easily track purchases made with it. If you have an American Express Gold Card, be sure to grab one of these. [Thanks, Sarcia]
