I would offer 4,000 credits. All you have to do is edit the auction and real close to where you put in your starting bid, you will see a block and it talks about gin, you would just put the 4,000 credits in the gin block and submit the update to the auction, its really easy. It does cost 50 credits to use gin, but when i buy it from you, they also return the 50 credits, they only keep that if it does not sale.
