Well, I've never done GIN before and I just read about it. You might be better off just bidding on the auction as I would set GIN at 5000 credits. Let me know if you still want me to list it GIN. Thanks for your interest and just let me know.
You bid with the credits you have and if you win the auction then you tell me what your verified address is and I ship it. I'm offering free shipping on this auction, so it doesn't cost you anything other than the credits that you use to bid with.
