Why don't you use
brawker.com? Amazing website that allowed me to buy a few things from ebay and I didn't have to deal with credit cards, paypal or other payment methods. Just paste the link of the thing you want, wait for a buyer, he orders it for you, you give him btc and it's done.
Interesting, so decentralized markets always come before centralized.
F2F trading is the real trading anyway, not buying from some nasty vendor who charges you comissions
