TigerDirect offers the factory-refurbished 5.5-lb. Acer Aspire Intel Ivy Bridge Core i5 1.7GHz 15.6" LED-Backlit Touchscreen Laptop
in Silver, model no. V5-571P-6499, for $482.14
plus around $8
for shipping. That's tied with last week's refurb mention and $24 under the lowest total price we could find for a similarly-configured refurb with an i3 processor elsewhere. It features an Intel Core i5-3317U 1.7GHz Ivy Bridge dual-core processor, 15.6" 1366x768 touchscreen LCD, 4GB RAM, 500GB hard drive, DVD burner, 802.11n wireless, Bluetooth, USB 3.0, HDMI, 4-cell battery, and Windows 8.
Note that an Acer warranty applies, although the period is unclear. Although TigerDirect doesn't stipulate that this is a touchscreen, Acer confirms that this model does include one.
