Even though prices have shot up for things like almond, soy, and oat milk, the size of refrigerated versions have always been 1.89L.
But I noticed some strangeness on the Walmart (Canada) website while building my grocery list where one brand, that is priced less than another brand, had a higher cost per 100ml.
As I looked into it, I noticed that several varieties have gone from 1.89L to 1.75L.
I noticed Silk and Earth's Own, but only several varieties/flavours at the moment. I expect all of them to shrink down to 1.75L once they sell out of the 1.89L sizes.
For Silk I've seen the 1.75L containers for quite a while. They are limited to the special varieties with more expensive ingredients such as the one with additional protein. I doubt this is an example of shrinkflation
