I would consider it. :) I just bought this system from ebay a few months ago for Christmas, But I over bought the systems and this one never gets played with. I spent like, $32 on it I think. So, to answer your question. I think I would consider free shipping if it goes past 3000 credits, and if I have to $ for shipping when this auction ends. :)
It would be $5.90 in a small flat rate. And yes, I will take a postal money order, but of course I would have to wait to ship the item until I receive the money order. :)
