As I understand it, a lot of these retail credit deals (for guns, furniture, what have you) often get sold as 0% for 3/6/12/whatever months. Of course the fine print always says that if you miss a payment or hang on past the zero percent time period you get clobbered with a godawful rate and fee.
There is not a venison market taht I am aware of, but you can sell squirrel tails, believe it or not.
