I just ordered the MX3100 Duo, which comes with this same mouse, so I'd like to get rid of the older mouse. I'll just sell it to the highest offer, if it's reasonable. Please don't post offers here, PM them to me and I'll get right back to you. It's really only a couple of weeks old, it was bought directly from Staples for around $55. There are no scratches or blemishes, and it comes with everything that came in the box, and it is packed in the orignal box.
