Best Buy via eBay offers the Corsair M65 Pro RGB Optical Gaming Mouse for $39.99 with free shipping. (Amazon, Newegg, and BH Photo Video all have it for the same price.) That's tied with our mention from a month ago and the lowest price we could find now by $20. Features include a 12,000 dpi sensor, three-zone RGB backlight, sniper button, and eight programmable buttons.
