as far as I know (and I know 0), a business needs to 1) increase the prices or 2) sell more stuff to stay alive. If they sell something that a) very few people can buy and b) never breaks, they will have a problem (unless they also sell coke behind the warehouse)
But usually, with my business sense, doing the opposite of what I think would work is the right approach. So, no, don’t sell coke behind the warehouse.
