If you are looking for AR or AK mags, and maybe for other rifles... there are boatloads of prebans at not too bad prices, but everything else is pretty much off the wall, although I scored some preban Glock mags, but I'd bet nearly anything that vendor is cleared out at this point... at noontime he only had a few left.
I didn't see much of anything else... lots of people with overpriced pistol mags otherwise. I also saw some jerkwad trying to sell a preban Mini-14 mag for like $120.
The show sucks for ammo, so if you're looking for a deal on ammo, save the $9 and don't go. Then again the previous Marlboro shows had poor ammo prices too... basically one vendor, no competition. (As a metric, in Concord NH Privi SS109 battlepacks were like $76. The one vendor selling lots of ammo at this show at that same product for $90!)
The chinese flashlight report was promising... seemed like there were down at least 1 or 2 junk flashlight vendors from last time.
