"Know what happens to most of the produce that's edible, has enough shape to survive in transit, but looks funny? IT GOES TO THE GROCERY STORES THAT POOR PEOPLE SHOP AT"
I've been to all of those places and other than the decor and maybe freshness they didn't seem that misshapen or blemished to me.
My understanding is that they, like many Asian markets, have exclusive long term deals with certain farms. Maybe only for certain types of produce?
Regardless, I find a lot of their produce, especially their greens, to be incredibly fresh and incredibly good looking — much better than what I can typically find at TJs or WF.
