OP - was the item listed in the  Everything Else > Information Products category in the classified ad format?

Unlike other sites where digital content is delivered together with payment, I believe that the seller has to send the information separately as there is no way on Ebay to pre-load the digital content. However, if the seller is listing anywhere else other than in the category above, they are in violation of the T&C's which may raise flags for authenticity.

What is the item number?
