My Costco has them too. I refuse to buy them. Costco introduced a 4 L container in one part of the country. There was even an article in "Metric Today." However, in many areas they are using the container but only filling to 1 gallon. The metric marking (3.79 L if I recall) is consistent with that fill, and there is a LOT of headspace (0.21 L of excess headspace to be precise). There are reports that the design (which saves space) is hard to pour without spilling. I don't know if they went to 1 gallon fill to help the spilling problem, or if it makes a difference.

It just may be labeled as one gallon to keep it simple. Have you verified the fill to know for sure?

A pint of milk certainly doesn’t seem like a lot, so I wonder why they delivered such a small size. In our house we go through three large Costco bottles a week. (These are the rectangular four-liter bottles that Costco fills with only one US gallon.) Carleton
