Not sure if I'm the average meal kit customer, but I don't choose to receive them every week. More like once every 2-3 weeks. Just something to consider in a customer's LTV.
According to their S-1, it seems as if their typical customer does indeed place an order pretty much every week. That certainly wouldn't be me. But, then, I think about using some of these services from time to time--but almost always end up driving to the store and picking up my own ingredients.
