My grocery store’s frozen crap has never been as good, interesting, or inexpensive as it is at Trader Joe’s. It’s not that the stuff there is great or cheap, but there’s a bit of variety that is harder to find in the Krogers and Safeways and they do switch things up so every few months there are new options. For me, between variety and C quality, vs the same basic American stuff and somewhere between F to B quality, I’ll take the former. That’s why I don’t really get frozen stuff at Costco.
