My wife called me a little bit ago to tell me that the online store wouldn't accept the number "0" when she used the upper number row, but worked fine from with the keypad.
*shrugs* I don't know whether this was the fault of software, hardware, or user, but I thought I'd mention it.
FYI, it worked just fine for me when I ordered at 1 am (Central timezone) this morning.
