I know many have negative feeling about WalMart. However, they have an excellent extended warranty program. Mine even covers normal wear and tear. If one of my keys wears out or the screen cracks, they will repair or replace the laptop... at no charge. I have this warranty on my Acer for 3 additional years beyond the 1 year manufacturer's warranty.
They also sell refurbished computers, although you have to look for them. It is at the bottom of the Electronics>Computers
section. You can purchase the same extended warranty on their refurbished laptops and desktops. For a college student, or someone who tends to 'break' computers, it is a good deal.
