On Black Friday, the Roborter was available for 499. However, there was probably a small glitch. On Google, the price was already 499 shortly after 0 a.m. On the homepage, however, it was only a little later. So much later that even google changed back to the normal price in the meantime.

..looked until 00:30 and nothing has changed in the price...ordered in D with suction station.
