First off, this company doesn't deserve one star, but you are forced to select something.
This company is terribly unethical. They charged my credit card 6 months after my original purchase for taxes, without my authorization!
They also did a terrible job of explaining the costs of the parts we bought, probably becuase the rep I talked to had no idea what she was doing and couldn't understand my questions. We were told one price and were charged a much higher price.
Bottom line: Do not use them...unless you want mysterious charges to show up on your credit card months after your purchase.
