I am extremely satisfied with Autoplicity in terms of service, price, and shipping. I was shopping for a set of N-FAB step bars for my truck and was ready to purchase from Amazon when I decided to look around to see if there were better prices. I stumbled upon Autoplicity and was surprised to see their price on the bars. I checked with their online chat customer service to confirm that they would fit my truck and that the price was for a pair of the bars and not just one. (That's how low the price was!). I then placed my order and the bars arrived at my doorstep 3 days later! Autoplicity gets an A+ in my book and I'll definitely be coming back.

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!

Very fast shipping and price is rite
