Staples offer the refurbished Brother Wireless All-in-One Monochrome Laser Printer which also copies, faxes, and scans, for $110. This $30 mail-in rebate cuts it to $79.99. With free shipping, that's $21 under our February mention of a new unit and $50 below the best price we could find for a new one today. It features 802.11n wireless, up to 2400x600 dpi printing, up to 27 ppm printing, Ethernet, and USB 2.0. Deal ends July 1.
Note: A 1-year warranty applies, although it's unclear who supports it.
