Re: Could I be Hacked? - [Not Hack Attempt]
I wouldn't worry too much about this. I'd say a good 1 of every 250 sales or so this happens to me. The customer fills out all the credit card info but checks money order instead of credit card and the cc info is discarded. Whenever someone wants to pay with check/money order I switch the order status over to processing and drop a note saying 'personal checks are subject to a 2 week hold. money orders are processed immediately. to change payment methods please call blah blah.'
they usually call and change the payment method.
