OMG! so much spoiling of OP's post
Just bought 2 cards from OP w/o Escrow
went first and he promised to replace card whenever they go bad , so yeah The seller is Legit
you do realize that he is using a throwaway account right? Once the cards start to go bad he can simply abandon the account he is using and start over with a new account.
He did not replace the bad cards he tried to sell wardwrick so why do you think he would replace the cards he sold you?
