Lidl & WHSmith
Possibly of interest if you are living in the UK:
Lidl is currently selling a desktop pencil sharpener for £3.49 (~ $5.50; €4.30). I don’t know whether this sharpener has rubber grips or not.
WHSmith reduced the price for some of their edding products even further and many WHSmith stores sell edding’s push-button marker for 49p (~ 77¢; 59c)
