Customer service was great making sure I ordered the correct part number. Best price. I'll be back

I needed a bulb socket set and wiring pigtail for the rear end of a '97 Corolla. Couldn't find that on the website, so I wound up purchasing one for '93-95 Corollas. Perfect fit. I tried to call customer service before I bought, but it was a holiday (US Memorial Day) and the wait time was tedious. Other than that, all good!

Very efficient and pleasant..just hope the items get here before the next snow storm !!

Ordered power steering pump and it was shipped to my home within a week. Great price. Satisfied with my purchase and I will be using Autoplicity again.

It was simple and easy to order!

It was fast, easy and you have stuff that most stores don't carry.
