Sad thing is, GOOD shops are getting harder and harder to find. Most shops support themselves by renting out costumes and selling pranks. A lot of them have case of standard dealer items (not bad stuff by any means, just standard stuff: invisible decks, svengalli's, thumb tips, copper, silver, brss, etc). They also usually have some larger kids show props. The dvd section will be some of the Michael Ammar Easy To Master series and a few Magic Makers dvds. But you're not going to find a lot of the new stuff in most brick and mortar shops.
A lot of these stores don't carry the "hot new items". Why? Because the the internet kills them when it comes to pricing. So a lot of shops just carry the basics for the hobbyists and newbies.
There are, of course, exceptions. Denny & Lees in Baltimore has EVERYTHING. Davenports in London has loads of stuff. Daytona Magic in Florida is wall to wall magic stuff. Fantasma in NYC has a big selection of cool material. But these shops are far and few between.
I love the accessibility of Internet magic. But it makes me sad that most of the brick and mortar places have had to either close up or severely cut back on ordering new inventory in order to stay in business.
