Walking around the electronic section at my walmart (central KY) found this Logitech MK520 with a $9 sticker price. Tought it was a great price for a nice wireles keyboard and mouse combo. Closest price i could find on google was $34.99 so I think this is a pretty good deal if you can find it.
Here is the link to keyboard for reference and also the link to Brickseek to check for stock and price.
