Tried to buy a part, somehow my card was declined, twice, even tho the money was in there, they even took my miney, twice, to the tune of almost $100. When I call they say they have no proof of the transaction and they can't help, even tho my bank statement says Rock auto.
Only use if you don't want your money, the part you need, or good customer service.
