Yes, but... Think about what condition they are in, price out what they would be sold for elsewhere. HPB is very convenient but may not offer what you could get if you sold them on your own. Especially if they are rare and in good condition. HPB like other used book stores often don't offer what you might expect. I would not want you to be disappointed.

Yes
I would think so, as long as it's in fair condition (not warped or torn). But either way, it wouldn't hurt to have them check it out :)
