Easy and Quick

All went well!

Great deal on my purchase. Tracking # given once order shipped 2 businesss days later. Good merchant.

So far experience is good, will see if parts show up as they say.

Quick and easy

The prices were so much better with Autoplicity I couldn't believe it was the same item. E-mail response came within an hours. Will buy from again.<br><br>Ok, the verdict's still out on this one. Autoplicity said my item was shipped two days ago (two days after ordered), but FEDEX indicates they've only received "shipment information", after four days. I'll follow up when I actually see the order.

Quick and easy

Impressed with selection and price. Saved over traditional e-tailers and they shipped within 24 hours. Excited to recommend AUTOPLICITY.

The buying experience was great You will get 5 stars if the rack fits my 2008 GMC

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.
