Arenanet are supplying the none authorised retailors. How are they getting the codes otherwise? mostly shady ways. Like buying from authorised retailers using stolen credit cards, then reselling on all those nice '3rd party market place' websites. in short: don't buy on websites.Wrong - Genuine game key wholesalers have them in bulk. I have looked into starting a retailor before. These keys where something I specifically asked the retailor at the time.
