SteelSeries takes 30% off sitewide with no minimum purchase required via coupon code "DV2011". That's among the best percent-off discounts we've seen from SteelSeries, although we saw a 30% to 50% discount last month (since expired). Shipping adds $4.80.

A best bet is the factory-refurbished SteelSeries World of Warcraft MMO Gaming Mouse (pictured) for $49.99. After the coupon above, it falls to $34.99. With $4.80 for shipping, it's $5 less than our July mention of a refurb and $25 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. A 90-day SteelSeries warranty applies. Coupon expires October 12.
