Shipping was 5.00 on a 1.99 part but considering ebay was asking 18.00 for it I'm very happy

Easy to navigate.

Very competitive prices and fast FREE shipping! Will do business with Autoplicity again!

Very good website. Easy to use. found the parts i needed and the order process was very easy since i could just login using my amazon account. Very convenient. Received my parts in a week.

I ordered this product and Wednesday in the morning and it was on my door step Thursday morning with regular shipping. The ordering process was super easy and the price was $35 cheaper than any other online retailer. The Rack is awesome, easy to assemble took me about 20 minutes by myself, put on my jeep hooked up the bikes and off I went, fantastic design, I highly recommend the Rola NV2 bike rack and highly recommend Autoplicity
