Hi,
In terms of condition, this looks like a nice one to me. Yes, there is slight creasing in that bottom corner but you could do far worse. I've seen a few sell in auction format over the last few months for anywhere between US$240 - US$400 at various conditions, so selling price is certainly reasonable for the convenience of buy-it-now.
If it's been on for a while, then no harm in contacting them directly to see if they are open to offers either ...
Cheers, Jared.
