AltaTac via eBay offers the refurbished Logitech M600 Wireless Touch Surface Mouse, model no. 910-002666, for $11.99 with free shipping. That's the lowest total price we could find for a refurb by $1, although we saw one for $2 less in July. (It's also $7 under the best price we could find for a new one.) It features touch navigation and ambidextrous design. A 90-day Logitech warranty applies.
