Various sellers via eBay take up to 50% off a selection of new and refurbished vacuum cleaners, with deals starting from $11.95. (The banner advertises up to 50% off, but we found deeper discounts of up to 79% off within.) Plus, all orders receive free shipping. A couple of best bets, with comparisons to new units: Warranty information for refurbished items varies via seller; if available, it can be found on the product page.

Update: Prices now start from $29.99.
