I have bought more "premium" Spotify 1 or 2 year accounts off this site over the last couple years that I could have paid for a 1 year REAL account with all the money I lost. Every last one of them has been shut down because Spotify eventually "closed the loophole" the seller was using. ANY warranty is useless because the seller will disappear the minute the shit starts hitting the fan and accounts start getting closed.
Why should THIS deal be any different? You can be sure it won't.
And why don't you list a price?
