Why are you guys paying so much for all that stuff you put on your cars, just incorporate as a company and open accounts where the demand is high, you'll have your products at cost price. Why would you pay 80$ for an aluminum ball on top of a stick! In the future you guys could expand and get tires and mags. The only catch when you open an account witn those companies you have to buy a minimum of what ever you want but if every body is ordering you should not have any problems with that.
