Why is the price of ballasts dropping like crazy?

any buisnessman worth his salt knows how to get around the tax issue so it isn't that trust me.

Hydrofarm, Lumatek, Galaxy, Quantum, C.A.P., Solis-Tek, Advanced Nutrients, Maverick Sun, Power Sun, Hypo-Tek, GrowMedics, NextGen.

How many of these companies were making digital ballasts say...5 years ago?

Competition will dictate your pricing points.
