Just to clarify, I'm not sure if iTrader can be requested for the service you're providing. Granted, it's only something I've seen posted on another CAG's TL, who is also selling XBL Cards cheap, but it's something to look into to cover all of your bases.
I'll hold off on leaving iTrader until that is approved by a Mod, but aside from that, the codes work great. Thanks Taboner!
