Newegg offers the Polk Audio I-Sonic Audio System with iPod / iPhone Dock, model no. AM3395-A, for $99.99. This $50 mail-in rebate cuts it to $49.99. With free shipping, that's tied with our mention from two weeks ago and the lowest total price we could find by $80, although we saw it for $10 less last month. It features an iPod and iPhone dock, 4-speaker array, AM/FM radio, and compact on-board amplifier. Rebate expires January 31.
