The Razer Atheris ambidextrous Bluetooth portable gaming mouse is down to $39.99 on Amazon. It has been selling for around $44 since early July but was going as high as $50 or so before that. This is the lowest price we've ever seen.

As a lefty, one thing I can appreciate is a good ambidextrous mouse. Use this mouse whether you're left or right handed, and it works no matter what side of the keyboard you put it on. With two AA batteries, this mouse will last up to 350 hours. It has an adjustable DPI that goes as high as 7,200 and Bluetooth technology for high performance.
