$25 gift certificate for Playstation

I bought a Playstation gift certificate as a gift without realizing that I wouldn't be able to return it. I didn't end up giving the GC and I don't even know what a Playstation is, let alone have any need for this. I'm selling this GC worth $25 for $20. I am sure there are lots of scams in this realm, and so I will give you my number and meet you at my address in case there are any issues. Also, very obviously, the code on the gift certificate has not been scratched off.
