They cancelled my first order because my billing address did not match my shipping address, and claim they sent me an email informing me, but I received nothing.
They cancelled the second order a week later, also without informing me. The chat service (LiveHelpNow) says "the order was flagged for suspected fraud and cancelled."
I have had problems with this company in the past, too. Their online interface is simply too dinosaur-era to trust. Do not do business with them.
If you MUST do business with them (they DO have good prices and product selection), CALL them, do NOT order online.
