When I saw the compact keyboard from the Logitech Mk360 Wireless Combo (that also includes an optical mouse), I fell in love with it and ask the owner where they got it and was told that it was obtained through Staples. That made me very happy as I could either order it online or pick up up at a store that is within 2 miles of my office.
I went Staples.com website to check out the selling price and saw it selling for US$39.99. To get the MSRP to see how much I would be saving, I went over to Amazon.com. There, the MSRP of the Logitech MK360 Wireless Combo was US$39.99 and a asking price of US$35.99 which is a 10% savings of US$4.00.
As I was about to order it, I saw one marked used and decided to check out the details. It was actually new but the packaging box was slightly damage. Since I am not planning on reselling it customers, the condition of the box did not matter to me and so, I was able to get it under US$20.00 (US$19.97 + NJ Sales Tax).
