One store, at the front of the checkout conveyer more than once. Employee said they sometimes had them in the freezer dessert section.
Other store, they were clearly in the freezer dessert section with the larger count packages @Rickibotta mentioned.
I don't hesitate to ask the workers regardless of the shop I am shopping where something is. Then to kindly check the back room if possible if no stock is on the floor.
Doesn't hurt to look around a bit sometimes too. I have many times found one of something out of place but available.
