Lowest price and S&H around! Prompt responses! Will def buy from again!
The price is right but shipping cost is high.  I bought a transmission seal for $12.91 and shipping was $13.31.  The box it shipped in was about 10 times bigger than the part itself.  Reduce the box and reduce my shipping cost please !  Else than that the part was in good condition, it was packed right and shipping time was reasonable.
No problems ordering a leak down tester from Autoplicity which had the lowest price and reasonable shipping charges.  The item was well packaged and I would buy from them again.
