Best Buy offers the Canon Pixma MX472 Wireless All-in-One Inkjet Printer, model no. 8749B002, which also scans, copies, and faxes, for $49.99 with free shipping. That's the lowest total price we could find by $28, although we saw it for $10 less after a gift card last week. It features a 9.7 ipm black print speed, 5.5 ipm color print speed, 4800x1200 dpi maximum color print resolution, USB, and 802.11n wireless with support for Pixma Cloud Link, Google Cloud Print, and AirPrint.
Update: It's now available for in-store pickup only.
