Host parties at your house, provide kegs for $5 a cup, and the biggest money maker, NITROUS for $5 a balloon, your first tank cost like $150 but you get like 100+ balloons, to refill after that its only like $30 bucks, think about the profit margin if you even go through 1-2 cannisters a week! and you'll make money off the kegs too... Plus on top of extra money you'll probably get smokde out alot more for hosting big kickass parties... peace
