OP says in this thread "Price start from 4-7$ with Warranty."
And by email he just said to me :
"Spotify [Upgrade your Account to Premium], 12$ (6 Months Warranty)
Spotify [Upgrade your Account to Premium], 20$ (12 Month Warranty)
Spotify [Upgrade your Account to Premium], 30$ (24 Month Warranty)
Spotify [Upgrade your Account to Premium], 40$ (36 Month Warranty)"
What a joke
