IMHO, DSC model (subscription based company directly owning supplier to consumer chain, offering nice price + convencience) is the way to disrupt incumbents in consumer goods even though they will never get as big or as strong. there are lots of products which we do not care which brand we purchase as long as a certain level of quality and on-time sufficient delivery is ensured. i would definitely subscribe to a service which analyzes my consumption and delivers all "non-critical" products to my home/work location.
You're thinking of Harrys, they raised money to buy up a German razor factory to do a full stack business.
You're also really thinking about house brands that your local Walmart offers that plenty of people already buy.
Walmart on a subscription model already happens, they get sales upticks every payday or welfare disbursement days.
Amazon's CPG division is also building up heat. Their house brand is swallowing up category after categories from the Alibaba to Amazon guys.
