Welcome to our website! As we have the ability to list several hundred items on our web site (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our web site.

However, if you are an American with a disability we are here to help you. Please call our disability services phone line at (254) 675-3515 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our web site, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for any American with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.
