However, if you have a disability we are here to help you. Please call our disability services phone line at 918-495-0586 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, 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 anyone with a disability.

Add two Gigabit Ethernet ports via the USB 3.0 port on your Chromebook, laptop, or other computer
Tripp Lite's U336-002-GB USB 3.0 to Dual Gigabit Ethernet Adapter allows you to quickly add two Gigabit Ethernet ports to your computer through a single USB 3.0 port - no need to open up your computer case to add an internal Ethernet card.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.
