Newegg still offers the refurbished Samsung 5.1 Surround Sound Home Entertainment System with Blu-ray 3D Player, model no. HT-FM45 , for $109.99. Redeem this $30 mail-in rebate to cut it to $79.99. With free shipping, that's the tied with last month's mention and the lowest total price we could find for a refurb by $70. (It's also $107 under the best price we could find for a new unit.) This home entertainment system features one HDMI port, one Ethernet port, one Optical port, DVD upscaling, and 500W speakers. Deal ends February 28.

A 90-day warranty is included, but it's unclear who backs it.
