My payment invalid......what?
The truth, they complicate the transaction to block the sale. They don't want you to use that credit card because it protects the customer.
I called Discover twice, they told me they could see the pending transaction, and that Rockauto uses an additional method or layer to approve the purchase thru your email or text which makes it show as invalid.
I had to throw the b.s. flag.....nothing wrong with my card.
This is the only company for internet sales that does this that i have ever seen. Go use another company.
