This place was great. Great service they really helped mr out and were fast and extremely helpful.

Awesome

Everything was quick and easy. With discount for shipping, best price I could find on the internet. EDIT: Only problem I had was that the two day express shipping I had was a day late. I also never received a tracking number before I called CS. That was q

Good web store front. Makes Parts Geek look like the trainwreck it is.

Ordered the Auto Ventshade Ventvisor Deflector 4 pc. (Model 94856) for my 2000 Toyota Camry XLE. Was easy to install with no tools, just use the included strong double sided adhesive tape. Instructions that came with it could've been more detailed on where exactly to install the ventshade as I had to remove them tediously, realizing I had to put them a little higher. Also, there seems to be an unsightly gap between the front and back windows. Works as designed. Satisfied with product. Fast shipping by Autoplicity.

An excellent combination of a terrific price on the Thule product I ordered and very fast delivery. My only regret is that I had to order the fit kit more my car from another vendor.

Helpful-reasonable prices-reasonable shipping-prompt.

shipped fast and great price
