$1.65 per cookie and six pack $9.50

I really don't remember but I wanna say $10

Yes. Depending on location. You can go to website and check if your address is in the delivery range.

They have deals on cookies in 6 packs up to 24 packs, the cookies come in boxes though. You can also order bulk deals on 50 to 300 cookies but I'm sure you have to call in advance.
