The seller's "red" trust aside, "1 yr Spotify codes" NEVER last beyond a month or 2 before getting shut down. I have experienced this at least 4 different times with 4 different sellers (probably the same seller under a diff name but who knows). By the time the account is put back to "FREE" the seller of course has disappeared. The latest one was a "NL" (Netherlands) account deal from seller "SPOTIFYGUY" there was also SONY and 2 others I don't remember but could easily look up. Since they are promos from out out of the country Spotify always figures them out especially if you are in the USA.
This was the last thread that was a FAIL:

Buy at your own risk ... you have been warned.
