Do they have a copy of Grey's Anatomy?

You can call and ask. He knows his stock

The stock is constantly turning over. Items sold, more brought in. For an up to the second inventory you would need to call the store directly.

I would be surprised if he didn't.

I would look at Goodwill first. I tend to find a lot bought at goodwill and marked up

I agree with Dave Bail its better to call the store.
