VM Innovations via eBay offers the refurbished Ninja Coffee Bar Coffee Maker with Thermal Carafe for $89.99. Apply coupon code "P20MEMDAY" and check out with PayPal to cut the price to $71.99. With free shipping, that's the best deal we've seen for it in any condition and $77 under the lowest price we could find for a new one elsewhere. (It's also $50 under our February mention of a new unit.) It includes a 43-oz. stainless steel double-wall insulated carafe, milk frother, permanent filter, double-sided coffee scoop, and removable water reservoir. Deal ends May 29.

Note: This coupon can only be used once per PayPal account within a single transaction. Additionally, a 90-day warranty applies, although it's unclear who backs it.
