Meritline offers this 2.4GHz Wireless Optical Mouse with Nano-Receiver in random colors (Blue pictured) for $5.99 with free shipping. That's tied with our May mention of a similar mouse without a scroll wheel (this one has a scroll wheel) and among the best prices we've seen for a wireless mouse. (It's also a current price low by $2.) This 2.4GHz mouse features a scroll wheel, on/off switch, up to 1,200 dpi, and more. Expect this item to take two to three weeks to arrive. Deal ends August 17.
