Ok, lets say every Wal-mart and K-Mart and S-Mart starts selling a big line of paintball gear. Do you want to see them put your local PB shop out of business. Cutting paint sells from your local shop's paint could do that, alone.

Is Wal-Mart going to help you find some nice used guns and gear when you need them? Will Wal-Mart being a 3rd party for your net trades? Hmm...
Wal-Marts could kill paint ball as we know it..
Besides, Small shops can sell new "newbie level" equipment at for just a little more... WOuld you guy rather see a new kid buy a Traccer S/A fro $75 at the local PB Shop or spend $50 n a stingray?
