Don't worry about it. I'm not certain of the exact postage on a gameboy game but I know I paid $1 for the postage for the last one I won that I had to pay shipping. Most people just want free shipping, it also will usually result in more bids. I have a coule things I'm bidding on before yours ends, but if I have any credits left, I'll be bidding. Is concealed cash acceptable for shipping payment?
