For some reason, they never show up on product locators but it could be
because, like Costco, you never know for sure what they will stock. In the
past I have bought Tillamoos and big bags of hard boiled eggs. But those
are no longer. Same for the Sopes or Sopitos or whatever they were.

Anyway... Decided to go down the baking aisle and there were the brownies.
Also saw various cake mixes, muffins and other things. Didn't see the icing
but really didn't look for it.

So I stand corrected. You can get those things here. Just apparently not
most of the things, anywhere but there.
