Best price I could find on the web even after paying for shipping!  Shipped in a couple of days and great service!
Fast and easy transaction.
This is a great e-retailer.  Best price and fast shipping.  I ordered a bike rack.  Their price was the lowest I could find, and it was drop shipped from the manufacturer the following day, and arrived in time for me to use it on the weekend.  The one criticism I would have is the item description could have been better.  From my web research, I knew the model I wanted, but if I was just browsing bike racks on their website, I would have needed more information.
