ok first off dude, how did you expect to pay for the shipping in the first place. i will accept both paypal and discreet cash. paying shipping by extra credits is not an option for anyones auction because you have no control over the amount of credits i end up with. if you havent noticed, the are proxy bidding auctions which means that no matter how many credits you bid, it will only apply the amount needed to be the winner of the auction untill someone outbids you meaning that even if you wanted to give me 1000 credits and somone elses previous was only 500, youd only end up giving me around 510 so paying shipping through extra credits is never an option.
