Quick and Easy. Best price I've seen by far.

Fast ordering system

Thanks

Was for head gaskets. They used to come 2 to a pack--now same price and there is only one in the pack (1135g) Mr. Gasket. Knowing this, I wouldn't have ordered.

Thanks

Easy and quick check out

The product came at the very last minute. So we had to do something different plus the "return" directions on the website were not clear, i.e. the return process is not easily executed.

Great prices, quick shipping, customer service a bit difficult to reach. But, after reaching customer service, issue was resolved without a problem.

Easy and fast so far

I liked it, I will return.

So far so good!

Excellent

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

Thanks for having the short shifter available !
