depends on what you are looking for..
ammo cans, probabally..
reloading components, yes
bulk commercial reloads, probabally depending on caliber
optics..not seen one yet..
classic revolvers.. sometimes..
classic autoloaders, and bolt guns..sometimes..
new stuff..I haven't found it to be a decent deal.. my LGS does better on new and most of the time used stuff..except for things he does not carry, mags, bulk ammo, reloading components, I probabally would not go..
