Fast, convenient, cheap
Fast, convenient, cheap - what more could you want? I've been using Lis-skins for a long time now. Trades and balance credits come through pretty quickly, and most importantly, you don't have to wait seven days because of “trade protected.” On the downside: payments via Ukrainian banks are not supported, BUT withdrawals are supported with a fairly low commission. (4 stars due to the lack of balance replenishment via Ukrainian cards)
