Generally you can expect to pay more for an item at a gun show than you will at your LGS,I have only found a handful of decent deals at shows in the past 5 years.
You can find some stuff the same price as LGS but most are a little higher. If looking for pistols or rifles, keep an eye out on the smelly people walking around ,you can find some decent deals watch for signs taped to barrels or on peoples backs.
Thanks guys. Im not looking for guns just reloading supplies. im wanting to find powder at a decent price.
Darral is correct. Lots of smelly people seemingly with IBS and lots of dangerous "knowledge" about firearms. Go have a look, can't hurt, just don't get your hopes up. Most shows have overpriced stuff on the tables. Better deals online or at your LGS.
