Part of their year-end clearance. The keyboards with Cherry switches are much better than the ones without, and at this price break they’re quite affordable. For reference, shipping to Launceston TAS is $13.99.
Here’s a direct link to the switch of your choice:
Blue Cherry switches
Brown Cherry switches
Red Cherry switches
Been this price for a few weeks now. I didn’t know enough about keyboards to know if it’s a good deal or not but and Kogan seems to talk BS about the regular price in general.
