If an item isn't marked for GSP but you are interested, you can contact me and we can discuss matters from there. If you foresee delays complying with this matter please just contact me ASAP so we can work things out. Anything I sell that deals in used/open software (video games, movies, CDs) or hardware is tested both prior to and after a successful sale.
Unless I specifically mention the item does NOT work or mention being unsure of its proper state, know I test and review what I sell every step of the way. If you're meticulous for details, rest assured I'm meticulous for the too. If you have questions feel free to ask, I'll try and tackle them usually within a day of receiving them. If something concerns you or you have follow up questions just message me. I'm more than open to talking you through any problems I'm knowledgeable in.
