SteelSeries takes 20% off sitewide via coupon code "ROM20". Plus, it stacks onto sale items. That's the best percent-off discount we've seen from this vendor since October, when they offered a 40% off sitewide discount. Shipping adds $4.80.

A best bet is the refurbished World of Warcraft MMO Gaming Mouse (pictured) for $39.99 via the above coupon. With $4.80 for shipping, it's $22 under the lowest price we could find for a new unit. It features 15 buttons, over 130 predefined commands for drag-and-drop macro creation, and more.
