To those that register and don't receive the codes, it is not because the auction did not send them, it is because your spam filter(s) on your server, and/or computer is seeing them as spam(because they are system generated), and filters them out.
You need to be sure to add the entire domain of LBLastChanceAuction.com to your white/acceptable list on any spam programs on your server or or computer.
There is a specific message written in red text at the top of the main auction page in regards to this, and has been there since the auction opened.
