Walmart still offers the Philips 5.1-Channel DVD Home Theater System with iPod Dock, model no. HTS3151D/37, for $147.88. Shipping adds $10.47, or opt for free Site-to-Store. Even with shipping, that’s tied with a deal from two weeks ago as being one of the least expensive such home theater systems we could find. Sales tax is added where applicable. Features include 300 watts of total system power, progressive scan DVD player with DivX, DVD+/-R, and MP3 playback, built-in Dolby Digital and Dolby Pro Logic II decoders, and component and RCA video outputs. The iPod dock includes eight adapters for many iPod models.
