They offer free dust cleaning for your computer either DIY or they do it for you. Reasonable prices and cheaper (or about the same) as buying online. They helped me with my computer. Not a large selection of computers for sale (at least compared to Best buy). They do sell desktops and laptops. They sell computer parts and accessories.
Pro-tip: wear a face mask and eye protection when cleaning dusty computer. You don't want to inhale dust bunnies or get them in your eyes.
