This deal is not for everyone but this is basically a wearable oximeter.
Been eyeing this for awhile now but never seems to be on sale and missed the last deal
The Wellue site has it at US$165 (https://getwellue.com/pages/o2ring-oxygen-monitor) rather than US$179.99 which is the usual price on Amazon as well, as seen on Camelx3 (https://camelcamelcamel.com/product/B08HDGBF7P)
However, for some unknown reason, the discount code from the previous deal (OZ30) works so brings it down to US$115.50 while still qualifying for free delivery.
Unsure why the discount code works since I've tried it in the past (after the last deal had finished) and it never worked before! Not sure how long the code will last though.
Anyhow, thought I'd share this in case someone else wants something similar.
