$489.00 in parker music store credit that I want to sell for $400 - $400 (houston, tx)

I bought a guitar from parker music a couple of days ago and I ended up taking it back and they stuck me with store credit and that sucks for me because i'm gonna fly home tomorrow. I will go to the store and use the credit for whatever you want. The amount of credit is 489.00 dollars and I'll sell it for 400. You can use the credit before you pay me. please call reed at 713-894-2484
