These are sometimes traveling circus shows. You can do well or can be burned. When these folks pull up the tents, their warranties/guarantees tend to leave town. You will probably find lots of "questionable" software there, repackaged accessories etc, among the new stuff. It's a gamble, really. Spend the 7 bucks to check it out, stay a while but don't buy anything during your first lap around the place. My advice only....have fun
Never been to one of these shows. It's in a conference center which is big. I need a printer, flat panel monitor and speakers with woofer. Do you really save money at these shows or can I do just as well at the box store sales. Admission: $7.00.
