My fiance and I are thinking about going if the taxes come back in time, is anyone else going to be there?

I've never been to an Expo, how are their prices, higher or lower than usual? Do the deals get sweeter as the day goes on? lol

Are there any vendors that I should stay away from? Are there any vendors I should run to? lol

Do they let you leave once you enter? in case we would want to leave to get something to eat and come back.
