The Wii Cordless Keyboard from Logitech is eligible for a $20 mail-in rebate until March 7th. Amazon carries the keyboard for $39.99 before the rebate, although it’s currently out of stock. If you don’t mind waiting a bit, though, you can buy it now and Amazon will ship it to you when it’s back in stock.

If you’re not the patient type, Newegg’s got it in stock for $44.99 before rebate although shipping adds about eight bucks. Buy.com has it for $49.99 before rebate with free shipping, though, so that might be your best bet if you want it quickly.

That $20 rebate (PDF link) is good on more than just the Wii keyboard, too. It works for a few of Logitech’s cordless mice, the MX Revolution and Wave keyboards, the X-540 speakers, and the Driving Force Wireless steering wheel.
