I'm setting up an auto accessories store, and was wondering what's the best way to sell tires and wheels combo's. The price for a set of 4 tires / or a set of 4 wheels is different than a whole set with tires and wheels. Setting up kit items doesn't work either because once I assemble the kit with a certain type of tires, it uses up the inventory, if customer want different tires, it will not work.
Any suggestions?
