Walmart offers the Curtis Premium 5.1 Home Theater System, model no. DVD5089, for $48. Shipping adds $4.97, or choose free Site-to-Store pickup. That's $22 off and a very low price for a 5.1-channel home theater system. (For comparison, we mentioned a refurbished 5.1 home theater system for $22 more last week.) Sales tax is added where applicable. The system features 450-watt of peak power and includes a DVD player, subwoofer, and five satellite speakers.
