As one of its daily deals, Newegg offers the refurbished Shark Rocket Powerhead Vacuum Cleaner for $49.99. Redeem this $10 mail-in rebate to drop the price to $39.99. With free shipping, that's the lowest price we could find now by $40, although we saw it for $10 less a week ago. It features two speed settings, removable and rinsable brushrolls, and a 25-foot power cord. Deal ends today.

Note: A 90-day warranty applies, although it is unclear who backs it.
