The cash register says $50 million dollars went into the car freshener business last year – an $8 million drop from the year before – and that means a lot of pine, rain, and cinnamon apple fragrance into car interiors.

Instead of more purchases being made, however, industry reps say the profusion of flavors are where the money trail leads. Little Trees' (pictured) site alone offers 97 different odiferous options.
