I've been wanting to try the Nest Doorbell for a while and I think this is the cheapest it has ever been:

Kogan First is free to try. I've had it before and cancelled it ages ago. I was able to activate the trial again and without having a payment method added to my account. I simply activated the trial, bought the product at a cheaper cost + free delivery, then cancelled the trial. If I want to, I can still activate it again now.
Out of all the options out there, the Nest Doorbell seems to offer the most features without any additional monthly/yearly subscriptions. I rarely find them at a good price. Even the 2nd hand ones on EBay are expensive (around $150 NZD) and I've only seen it listed at a decent price on FB Marketplace & Trademe just once. The other listings are expensive. I think at this price for a brand new one, it's worth a try.
I've also made a more in-depth post on video doorbells a while back in case anyone is interested:
