Thumb Score: +29 Best Buy has the Logitech G502 Lightspeed wireless gaming mouse for $104, on sale from $150. Free shipping or store pickup. Comes with a 15-day return/exchange window. These seem to go on sale for ~$100 fairly often, but I figured I'd share it in case anyone's in the market right now. This is a well-regarded wireless gaming mouse, and my personal favorite.
