Does anyone have any experience with buying gift cards from egifter using btc? It seems that people have success using gift cards to refund, but how many times can you use each card if a new acct+address is used each time and the value for each purchase is <$100? Which websites are the best for gift cards? I realize refunds less than $100 are arguably not worth it, but I have a (hopefully) long term method for this to work on. Thanks for any input.
