Got a bunch of gift cards you haven’t used yet? Sell or trade them the new site CardAvenue.com. For example, you could swap an unwanted $100 Pottery Barn gift card you just got for a $100 Home Depot gift card that you could really use. I’ve already spent my $200 in free Target gift cards, but maybe I can pick some more up at a nice discount. At least for now, the site looks to be supported by advertising, and does not charge any fees to buy, trade, or sell. All you have to pay is postage, which hopefully will lead to better prices for both buyers and sellers.
As with any other person-to-person system, you have to watch out for fraud. CardAvenue try to avoid this in a variety of ways. They are able to check gift card balances ahead of time, and also have an eBay-like feedback system. If something does go wrong, you must use the PayPal claim system (you can only use PayPal), and then their own CardAssure protection system (up to $100). I’d still be careful.
