Yes most real mil stores do have much better prices on real mil gear. Airsoft stores will do a good job price wise on replica gear.
Ranger Joes is a good store. I've been using uscav.com more though. If you want the real "Gucci" type of "Geardo" gear go to SKD Tactical. www.skdtac.com.
If you are looking for budget Mil Surplus/new tactical geat take a look at Major Surplus and Survival: http://www.majorsurplusnsurvival.com/ They're kinda like Cheaperthandirt.com, but their shipping fair if you live in CA. BUT there web store engine sucks.
