For those who understand supply chain economics, inflation hits specialty items exponentially harder than standard items.
A basic reason for this that over larger volume you can afford to have a lower margin than when the volume is much lower.
I'm one of those images they compare store brand mayo with gefen. The comparison is ludicrous. You can't even compare gefen to a name brand like Hellman's. It need to be compared to a specialty Mayo for proper comparison. You'll likely see very similar results if you don't be comps correctly.
You can't compare CY milk to your local store brand or even to a national brand like Dean or Hood. If you compare to locally sourced or specialty milk, you'll find the pricing far more similar.
For example, a 1/2 gallon specialty milk in stop mad shop sell for $3.49 and CY milk sells for $3.69.
This is why many out of town communities find it cheaper to bring in CY than produce their own. I could easily set up a CY operation locally for our community but the price would be the same or higher than bringing it from NY.
One of the main driving forces for pricing is volume.
