Newegg discounts over 600 items during its 12 Days of Techmas Sale. (Some items require additional coupons or rebates to yield the discount; these are marked on the product page.) Even better, get an extra 10% off when you checkout with MasterPass by MasterCard and apply coupon code "MASTERPASS". (A $50 maximum discount applies per order and it won't stack with other coupons.) Plus, most items bag free shipping. Discounted items include laptops, monitors, desktops, hard drives, audio, and peripherals.
