I was looking to sell a couple of bitcoins.

On localbitcoins, I see several individuals who are apparently in the business of buying AND selling bitcoins.

And yet, they buy at ABOVE the market rate. For example, right now BTC trades at 652.62, but bitcoinofamerica wants to buy at 666.78.

Does that contradict no-arbitrage market laws? Is there anything suspicious about this user?
