You can save the most money when you buy paintball equipment in bulk.  Volume paintball supplies are often bought by start-up fields, stores and paintball teams.  Military and law enforcement units also often purchase paintball guns and gear in bulk to practice realistic tactical missions.  Every penny counts when outfitting a paintball team with equipment, so cheap paintball packages and discounted guns and jerseys can make all the difference.  Bulk CO2 tanks and refill stations are also items bought in bulk by paintball teams, fields and military groups.
