I sell to a place named MWE however, they operate on a completely different method. They have a list of trusted sellers and what server(s) they cover. When MWE needa gold on a server they alert the sellers on that server via instant messenger/email/phone. Seller advises of stock on hand or how long to gather it. They do the exchange via their own accounts face to face trade, they send money via paypal and they sell it to their private clients. No website, no bullshit just straight business.
