I tried to visit Backstage in August. Even though the flea market was teaming with customers, the magic shop was roped off and closed. There was a sign hanging on the rope that said "back in 30 minutes". My patient wife and son waited with me for over an hour, and the store never opened. Perhaps you should call the business before making the trek to the flea market, to make sure that they will indeed be open when you arrive. From the looks of things , it seemed like a well stocked store. I saw lots of brass items in one case that was visible just past the rope. Wish I could have gone in and spent some money !
We did get to Magic Max in Olde Town, and bought a few things, but you should know that the store charges higher prices than the company sells things for on their website. One way to save a bit is to sign up for the Magic Max club online. We were given a 10% discount at the store for being members, a good deal since it was free to sign up !
