Office Max offers the Cooler Master Storm Xornet Gaming Mouse, model no. SGM-2001-BLON1, for $9.99. Opt for free in-store pickup to avoid the $9.95 shipping charge. That's the lowest total price we could find by $5, although we saw it for $2 less after rebate last month. This wired mouse features five buttons, 2,000 dpi, and rubberized anti-slip design.
