I've found this keyboard for $18 (about $21 with tax)

65% layout 2.4ghz, bluetooth and USB-C connectivity, red switches, hot swappable (can change the switches), double shot keycaps, up to 6 months battery life off 2xAAA, even the keycaps alone are worth the asking price if you were to buy them separately.
It ticks a lot of boxes, I was going to post it as a deal but I'm having trouble checking out.
I just wanted to see if anyone else that might be interested in it might want to try buying it and posting the results?
It does say welcome deal so it may be for new users only, I've tried checking out 3 times but I think the first 2 times I had the address wrong and the 3rd time it says "Lock benifits user failed"
Looks like my keychron, but with a better feature set.
Comes in at $30 after GST paid with paypal with no coupons, which I agree is a pretty good price.
