If u wanto to buy a unique from Archlord the only way is to avoid scam is buying with ingame currency. Cuz paypal and all is too risky they get the money and give u nothing and i dont think many ppl will give you the item first then check for money. so there is no way
there is the 50% 50% trade lol
u pay 50% then u trade and then u pay 50%
so u can loose 50% if the dont trade u and the seller can loose 50% if u dont pay the other half so is no good either.
too many ppl scamming so is better not to buy uniques or Accounts there is no way to avoid scam
just buy gold and coins and buy ingame
