Great job

I had to contact autoplicity as the website had the wrong description of the item. The person that was able to assist was very knowledgeable and assured me that the description would be changed. That was last week and as of today, the description remains as is. However, and more importantly, I received the gauge quite quickly and it is the one I needed. So on that they did a great job!!!

Fast and easy

thank you

Great prices.

It was easy and delivery didn't take long.

The description for the Trimax adjustable receiver hitch did not always include the drop and had to be gleaned from the part number.

Ok so far

Checked everywhere - lowest price on the web.

They had the best price I could find, anywhere, for Royal Purple HPS oil (and I spent hours searching). I ordered a case on Sunday night and it arrived on Wednesday (standard shipping) from half-way across the country. For standard shipping, that's pretty fast. They must have send it out early Monday morning, at the latest.<br><br>I'm very satisfied with my experience, and I'll definitely be ordering from them again, when I need another case of oil.

Excellent low prices and very fast shipping! Will do business with this company in the future and tell everyone else about it!! Thanks Autoplocity!

Shipping is high but I need the product.

Smooth transaction
