When I first started using Blue Apron a year plus ago, I found the meat to be generally pretty high quality, as good or better as what I could get at the standard grocery store picking it out myself (rather than a "premium" one like whole foods or whatever), and better than Trader Joe's'. (around me, the standard grocery store has pretty crappy meat).
My sense is that meat quality has been going down, but I dunno, maybe it's exactly the same meat and the novelty has just worn off.
My sense is also that Blue Apron has historically had higher quality ingredients than some competitors, but I can't say that for sure, and am not sure it continues to be true.
