Alas, that is true. We found some great freeze-dried mandarin oranges in Tennessee a few years ago, but none of the Costcos here in NJ had them.
Currently, I’d point out the Kirkland chunk light tuna, which is chunks (not a paste like so many brands) and is harvested sustainably. It also tastes like tuna used to taste when we were children.
I also liked the grapefruits I just got there, but the problem with produce is that it can be so variable. Mark like the dried mangoes, but he liked to “two-tone” (green and yellow) dried mangoes even better. Alas, they don’t have them any more.
