I think that it would be very helpful if you add PayPal as a payout method aswell. Many people/sellers on Gameflip would prefer that as a payout method. Personally I prefer it as a payout method aswell. If you can add it or discuss the topic with the Gameflip team it would be highly appreciated.
So this is something they removed a while back because of negotiation issues. I doubt they’re adding it back at a whim, without serious reconsidering. But it’s something I would like as well.
