I love to visit BPS. They are all a little different, but you can count on a fish tank, and some stuffed animals. When I go to the one in Orlando with my friend, we have been known to spend a few hours out front playing checkers. It is also great to browse, and some of the workers are pretty knowledgeable. Talked to one guy there last time for about an hour about smoking ribs and other food along with smoker designs. I've found some stuff there, I have not seen in some of the stores local like Sports Authority or Dick's.
That all being said, they can be pricey. If you want to buy something, I often check online prices. Like lamebeaver, I shop online mostly. I like to read reviews and check around for prices.
