Hello there, I have some question about a service offered by various member of this forum: the sell of serial numbers and the refund of a product. How does this work? I need to have the product before I buy a SN and receive a refund? Or can I buy SN and get product without having never bought the product itself? Is there something that I have to know about this practice? Thanks for the support, I really need help to use this service! Bye, Sn1mpuls3.
