In the wide world of bookstores, Bookstar is just okay. And while they do have a decent selection of books at the usual bookstore prices, they're still not as big as a Border's or as cost effective as Bookman's.
And to my knowledge, you can't sell any books back here because I've never seen a used section, so a star is taken off for that. But if you do want to get someone a nice book for a gift, this store would do just fine.
But if you're an avid reader, you definitely should start perusing the second hand book stores to help yourself save some money. You can get great books for super cheap and many let you sell your own books to them for store credit.
