Audiolab Stereo & Video Center via Walmart offers a pair of ELAC Uni-fi UB5 GEM Bookshelf Speakers, model no. UB51-BK-BLM, for $399 with free shipping. That's a buck under our June mention of an open-box unit and the lowest total price we could find by $100. Features include a 5.25" woofer and 46Hz to 25kHz frequency response.
Of note, several merchants are price matching these speakers, including Amazon and Crutchfield.
