There's a few sites that have cropped up - gift card drainer is one of them that pays either to bitcoin or paypal, with a fee structure that is based on the cost of the currency handling plus a flat transaction fee, with the USD pegged to the bitcoin, so utlimately everything is calculated in USD and then divided by the current exchange rate for BTC. It appears that the site administrators, however, are doing some impromptu research into the legality of the operation. I hope that someone figures out a good solution because I am nearly swimming in a bunch of gift cards that I would very much love to turn into bitcoon!!!

Good luck!
