Yes they will buy them!
Call them and ask. I have purchased new there.
Yes. Just remember that you're not going to get your money back for them as you're selling them to be sold off again and they have a business to run. You'll likely only get a good amount if you have a new copy of an in demand title.
They have new ones plus they will buy or trade
Yes they buy new and used. Although you will probably still get the same price for them new as you do for them being used
Yes. New and used.
