Staples offers the Logitech M325 Wireless Optical Mouse in Bubbly, model no. 910-004165, for $9.99. Plus, Staples Rewards members qualify for free shipping. (Not a member? It's free to sign up.) That's the lowest price we could find by $3, although we saw it in another color for $4 less in December. This mouse's wireless receiver features a compact design, so it can be left in your laptop's USB port.
