I've tried to order this thing a couple times, and I keep getting this message from Paypal:
The card you entered cannot be used for this payment. Please enter a different credit or debit card number.
This happened when I tried to order my Seat Concepts kit, too (I called Seat Concepts and was able to give them my CC # directly).
Does anybody here know why Paypal won't accept my Mastercard? I've used the same card for decades, never had a problem, have a high credit score, and don't have any other credit card to use (nor do I want one).
