maybe I should've prefaced my post by stating that in a previous life I was a tomato geneticist, so I'm very familiar with the travails of buying tomatoes from a regular grocer. that said you can find some acceptable stuff if you know what you are looking for. i cannot grow tomatoes yet in my climate, though with temps in the 70's for the next several days, if they stay there, i will probably plant my early plants for 2024 in about 3 weeks then another wave of planting in about 3-4 weeks after that.
cherry and cocktail tomatoes are not picked green and gassed. but other types, yes, this can be an issue.
