Getting pissed at rock Auto

I've been buying from them for many years. I think I only had a minor problem only once. As said above, even with shipping from 3 different warehouses anything is still cheaper than the local parts houses.
A guy down the street works on a lot of customer cars, mostly paint and body work. He was working on a guys 69 Road Runner and needed to rebuild the front end. He doesn't have a computer and does nothing online. I got him all of the Moog part numbers. I told him I could order it and save him some money. He told me the parts must be seconds. Anyhow I priced my list, and it was around $350.00. He declined, and ordered the stuff from our Car Quest that he said he gets a discount from. A couple weeks later, I stopped by and he had gotten all of the parts. He said it cost him right at a thousand bucks for the same parts. What a fool?
