Yup, still showing for sale on Kindle here for $2.22 US, also tried visiting via a US VPN:
https://www.amazon.com/Good-They-Cant-Ignore-You-ebook/dp/B0...
But I'm in Australia, so it's possible it's an Australia-only sale, even though I'm looking on the US site.
Edit: Also, here's the direct Amazon Australia link: https://www.amazon.com.au/Good-They-Cant-Ignore-You-ebook/dp...
