Tanga takes up to 55% off a selection of refurbished Apple MacBook Pro Laptops and iMac All-in-One Desktops. Prices start at $349.99 for desktops and $454.99 for the laptops. Plus, free shipping applies to each model. Deal ends February 2. A few best bets, compared to refurbs elsewhere: A 90-day warranty applies, although it's unclear who supports it.
