I think I’m more bothered by the fact that it’s 15 eggs rather than a dozen or 18. I’m used to seeing eggs in multiples of six. This is weirding me out.
I haven't thought about that, haven't bought eggs for almost a decade so I generally don't look at them. I think it's a brand thing now that I looked at different store sites, some are 6, 12 or 24, others are 10, 15 or 30.
At least those are even numbers. 15 doesn't even make sense to me from a packaging perspective. I would think a square 4x4 carton of 16 would be more efficient to pack in a truck than a 3x5 carton of 15.
Why? We generally get 3x6 or 4x6 cartons in my area, which aren't too different from 3x5 dimension-wise. Longer cartons are better IMO since they make better use of fridge space. I would hate a 4x4 carton BTW.
