My friend spends a lot of time taking advantage of a local chain's loopholes...
He pawns his crotch rocket every winter for around $100. So he makes minimum payments all winter which is like $10/month for indoor storage. Then he pays it back in the spring when riding season rolls around. Every time he makes a payment, he gets a 50% off any item coupon... This results in some amazing deals. He has exposed several loopholes like that and has made out like a bandit.
