Fast and easy. Inexpensive parts.

Shopping was fast and easy, however tracking my package was a nightmare. Went to their site and put in last name, order number, and zip code and there internet system could not match me up with anything. Called customer service and they could not provide any information. Said they would send me an email when they found out anything. Called later that day because I had not received an email, still no answers. Had them call the warehouse to get information because they just sent the warehouse an email. Surprise the warehouse did not pickup the phone. While I was waiting on the customer service rep to get back to me after calling the warehouse (I was on hold) the door bell rang and it was UPS delivering my product that no one could give me any information on. These folks need to fix something really bad. Anyway I gave the product 5 stars but everything else gets a 2.

Was easy to find item, price was okay & checked out fast.

It was great, you had excellent prices, and the 2nd day shipping was better than most competitors.

Thanks for making it easy to find and order what I need.
