I seem to have lost my Logitech Anywhere MX mouse from 2002 during the flight back from China and need a replacement. I love the size and versatility of the mouse and how it works on any surface. The Logitech MX Anywhere 2S would be the obvious replacement but it is £80 right now. Does anyone know of a site that I can add items and it will alert me if they gone on sale by monitoring all the main sites. Alternatively, does anyone know of any good alternatives?
