“it does give added reason to be makpid on cholov and givinas Yisroel”
I’ll be sure to keep this in mind when purchasing cheese in Serbia.
“I wonder why I don’t see gallon containers of Chalav Yisroel in local stores.”
It doesnt make sense for the producers and sellers. As a general rule of thumb, the larger the size, the lower the unit cost. In the case of milk, if for example, half gallon sells for $2.99 – a gallon will sell for say $4.79 (not $4.98) this is true of the quart and half gallon sizes sold already. You the consumer will buy the same gallon of milk whether you buy it in a gallon container or in 2 half gallon containers. From the perspective of the milk company, why should they leave 20 cents on the table gallon after gallon. From the perspective of the store owners (no I didnt measure, but I did ask a store owner in my neighborhood about something similar), more shelf space is required for a gallon bottle than 2 half gallons. the store owner puts less product at a lower price out for his customers. How does he win? Of course given the average family size, bli ayin hara, of the chalv yisroel consuming family, gallon sized containers makes a lot of sense from the consumer perspective.
