I'm a Blue Apron customer, I like it pretty okay.
But I've thought for a while that:
A) I wouldn't pay any more than I am now for it (in fact, I keep looking around for cheaper alternatives, but there aren't any, probably because...)
B) I suspect they can't make a profit at what they charge.
(especially cause as time goes on, I skip more and more weeks, further cutting into their per-acquired-customer revenue. Either I'm just getting tired of it, or my suspicions that each month the ingredients get cheaper and cheaper are correct, perhaps in response to B above).
I don't expect them (or their competitors) to stay around.
