Staples offers the Motorola Arris Surfboard 600 Series DOCSIS 3.0 Broadband Cable Modem, model no. SB6183, for $99.99. Pad your order over $100 (these paperclips cost $1.29) and pay with Visa Checkout to drop the price to $74.99, excluding padding. With free shipping, and factoring out padding, that's $5 under our mention from last month and the lowest total price we've seen for a new unit. (It's also a current best by $22.) It features download speeds of more than 600Mbps and upload speeds of more than 100Mbps. Deal ends July 23.
Note that this modem may not be compatible with all service providers.
