Save Smart via eBay offers the open-box Apple Magic Mouse, model no. MB829LL/A, for $33.99 with free shipping. That's $18 under the lowest total price we could find for a factory-sealed unit and the best price we've seen for a new one. (It's also only $4 more than our Black Friday week mention of a refurb.) This Bluetooth-enabled Magic Mouse allows users to click, scroll, or swipe via its seamless top shell. It requires two AA batteries, not included.
Note, while this item is new, it may have slight blemishes.
