なんか残念

I've been feeling disappointed recently.
Because my favorite items seemed to be exited from the shelves of AEON which is a supermarket.
I think they had collected good evaluations.

They had been one of AEON's private brands so they had displayed with other PB items.
When PB items had displayed, usually one item had been lined in a row respectively.
However, my favorite items had been lined in two rows respectively.
I think two rows indicated popularity.
Nevertheless, AEON decided to discontinue my favorite items.
Why? I don't understand the reason.
Do ingredients costs increase?
Anyway, I feel down.
By the way, my favorite items are プチクラッカー and はちみつかりんとう.
