Here's a deal that really computes: Best Buy is slicing the prices on all their Windows 8 touch-screen computers by a hefty $100. Take pick from Asus, HP, Acer, Sony, and other popular name brands that are known to be trusted. As a little thank you for your business, Best Buy will also throw in a free screen cleaning kit (all that touching is sure to add fingerprints!) and will ship everything free. New lower prices are already displayed, toss one in your shopping cart soon, as this offer's ending is unknown.
