Go to the link at the bottom of this post.  Sign up with a fresh email not already in Logitech's system.  If you're lucky, like I was, you'll eventually(soon) get an email with a coupon for 50% off most of their stuff.  Does not work with the Revue or items already marked down.

For example, I grabbed the Logitech G510 keyboard for 59.99, however it appears they have marked it down to 99.99 so I don't believe you can use the coupon with it.  Worth a shot though if you are in the market for a new keyboard.
