Each chip credit represents a discount of $25 for buying chips, but you need to buy at least 100 of them. So unless you sold them on day one the credits seem kinda worthless now. I'm buying them for BTC 0.01 each. Yes this is cheap, don't bother noting the obvious. If you are interested, reply in this thread or PM me. Escrow is fine by me, as long as you pay for any charges.
