Not the cheapest historical, but decent prices going on TP-link Deco M5 on amazon.
There is an offer available for a free KC115 smart camera via redemption with the 3 pack, but it states this is for participating retailers (not sure if this includes amazon) so maybe try and price match somewhere if you want this. I price matched at HN, but they would only go down to $236, this was perfect for me as I get a 7% discount on HN gift cards through work.
Setup was super easy, and wish I did this ages ago. I use the telstra home 5g broadband because NBN was never connected at my place. Previously I had the modem in a spot that was central to the house for wifi coverage, but wasn't great 5g coverage. With the wifi mesh I have now moved the 5g modem to the front window and my speed test results have jumped from 27/12 up to 161/20!
Edit: Price for the 3 pack has gone up to $245 (was $219 when deal was posted). Have edited the title rather than mark as expired as its still a decent price.
