I'm in packaging manufacturing, and you wouldn't believe the amount of businesses there are that buy someone else's chemical/recipe, have someone else make the bottle, someone else be the copacker, someone else warehouse and distribute. All they do is marketing and make BANK.

Normally I'm not a big fan of excessive middlemen, but that's just a good service. It allows the company they contract for to be more lean, while likely gaining more bulk discounts and such. That can be cheaper and more efficient than directly hiring people to do the job.
