Hi,
This problem is quite important... In doing "sandbox" testing, I setup a test download product for 1.95. I entered all the info for purchasing, but, left the expiration date as invalid. I then got a declined error from the server because of the invalid expiration date. I then hit the back option and there was a serial number listed for each failed purchase attempt. So as you can see, the serial numbers are showing BEFORE the successful purchase.
I then went back and corrected the date of the credit card, and made a successful purchase, but you can see I got multiple serial numbers, but only paid one time.
Thanks for any reply on this. This is quite an important issue.
Steve
