"The cheapest Mi Band 4 model is set to cost £34.99 (about $44, AU$65) which is quite a bit more than the Chinese price of CNY 169 (about £20, $25, AU$35). In China, there's also an NFC version that costs CNY 229 (about £25, $33, AU$48) but there's no word on that coming to the west."https://www.techradar.com/news/xiaomi-mi-band-4-release-date-price-specs-news-and-features
