Office Depot sells printers at very low (or even negative) margin, and then inflates the margins on cables, paper, ink, and warranty. If you want the best deal, get the printer from OD, and everything else you need somewhere else. That $20 USB cable they sell costs them $1 and you can get the same or better online for $2.68.
Careful now buddy, the internet is no place for common sense acknowledgement of reality.
