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.

Great price on a great product! The Thule Raceway 9002 3-bike trunk-mounted rack is what I purchased. Shipping was fairly quick and the product was new, in original packaging and was a great deal compared with other sites for the same product! Would order again!

Was linked here by Amazon. I found the absolute best price on the item I was looking for, I had a confirmation as soon as I ordered it, and shipping as prompt. I would definitely recommend these guys and will be shopping here myself in the future.

great pricing, and easy to use web interface!

smooth transaction. good seller.

"Excellent price and great customer service. Order was shipped promptly!! Would do business with them again. "

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

Item arrived promptly (4 days after order), price was good and item was as described.
