Fry's offers the Vonage Whole House DECT 3-Handset Cordless Phone System, model no. VDV23-CVR, for $100. This $100 mail-in rebate cuts it to $0. With free shipping, that's tied with our October mention as the lowest total price we've seen. (It's a current price low by $80.) It comes with three handsets, a base, and two extra chargers. Features include caller ID with a 30-number history, 30-number phonebook, handset transfer, and DECT 6.0. Rebate expires February 1.
