I've been watching the price of this keyboard for a while, and finally it's on sale, yes, the beauty of this deal is that you rarely see this keyboard on sale like this in these big brand electronic or office stores. Now with this price you can go to whatever your preferred local store to do the price match to sweeten the deal and use your otherwise useless GCs, for example, I remember Staples has 110% PM policy, and OfficeMax has 115% PM policy, etc. In fact, this price is even lower than the current Amazon price (yeah I know, it used to be $39.99 there, but not for the recent weeks).
For those who dislike spending so much money on a keyboard, this deal is not for you, or you may not realize this - this is the most comfortable keyboard I've ever experienced, and I just bought a second one for my office use.
