I received a "Credit Card Problem" e-mail and was informed my card could not be charged, so I filled out another order and submitted it... only to receive the same e-mail again.
I go to my online bank statement, and lo and behold I've been charged twice. What gives?
Both charges were voided because of incorrect card information. The voids won't show up until about a week after the charge. Or according to this wiki entry: http://en.wikipedia.org/wiki/Authorization_hold the transaction won't "fall off" until then.
