Appreciate you having the product I needed. At a reasonable price.

The description for the product is wrong. This is an 8 bolt posi and you advertise 10 bolt. I have the product I wanted (8 bolt) bc I knew what part number I was looking for, but it's still confusing when the description says its 10 bolt.

Thxs

Arrived on time and packaged well.

Got what I needed for a good price.

Thanks

Had the product I needed at a price that couldn't be beat. The shipping was a little high, but not completely out of line, either, and it was still better than other companies who have even MORE ridiculous shipping rates. Will buy from them in the future if they have what I need.

Autoplicity rocks! I ordered a tonneau cover on a Monday morning, and received it Wednesday afternoon. The shipping was ridiculously fast, the price was way lower than anywhere else, and the customer service was very helpful. I would highly recommend Autoplicity to my friends. Thanks for the great service and great product.

Awesome and fast service. Received product in 3 days! Will definitely shop here again.

Your prices for Metal Rescue were the best I could find and your shipping was fast, although I screwed up and ordered a quart when I though I ordered a gallon
