Groupon offers the factory-refurbished Vizio Soundbar with Wireless Subwoofer, model no. SB4021E-A0C, for $99.99 with free shipping. That's tied with our mention from last month and $68 under the lowest price we could find for a similar, new model. It features a 40" soundbar and 90Hz to 19.5kHz frequency response. A 30-day Vizio warranty applies.
