I yet to read all about all the quirks about selling but I was wondering, if I were to sell a RMA set of RAM from gskill (with in mind that I think the lifetime warranty still is there) how do I sell it so that the person can take advantage of that warranty? First of all I need to double check about whether there is still a lif time warranty, and then is it safe to send to send a copy of the original invoice so they can RMA it if they have problems? Mark out confidential info?
