Found this in the store yesterday. Manufacturing date is around July 2023 so should last for a few years if stored in a dry cool place.
Same brand and active ingredient as this:

I have been using the one in the link above for the last year with no issues.
There was another tag which said $33 but each container has a sticker near the barcode marked as $25.
