I can think about a lot of painful memories about going to the magic shop in the late 1940s, buying something for a few hard earned dollars I got from working at the corner grocery, picking cotton and chopping weeds for neighbors.
One item I bought was with a drinking glass, might have been the hydrostatic glass, and dropping it in the bathroom sink and breaking it. Yes, this 10 year old cried.
But that is small potatoes thinking about stuff you buy today for $150 and finding out the trick is done with magnets or a piece of thread, or materials you can get at Walmart for a cupola bucks. But then, you get a DVD, and that is suppose to cover the $145 markup.
Now think about this, you can buy a $500 trick for $46 at a Chinese magic store.
