B
Incredibly low prices and fast shipping. I bought shocks and struts for my truck and saved more than 35% over what my local parts store wanted!!! I made the mistake of not setting up my account before placing my order so I didn't get confirmation right away, but one quick phone call fixed that. Great customer service.
