I noticed on my Costco run yesterday that the normal 2 cartons of 18 eggs has now become 30. Same low price though!

I think we buy the same eggs, and I normally buy the same pack of eggs every couple weeks. Throughout the pandemic, it alternated back and forth between the two sizes, so I'm inclined to believe it's a supply chain issue (in packaging). But I'm pretty sure the 30 pack is a buck or two less than the 3 dozen pack.
But I have certainly noticed that some items at Costco are much higher than they were this time last year - sadly even they are not immune to the issues we've been seeing with food inflation.
