Same happened to me, but they not only charged me for the part, but for 2nd day FedEx shipping. Two weeks later, no product. Only after I called did they send me the headlights--the non-adaptive ones.
They refund my money, but only for the part, not for the tax and shipping.
I'm going to document this in correspondence to them, contact the Better Business Bureau, and take whatever action is necessary to rectify this. Buyers beware.
