A more sensible solution would be to have standardized reusable containers. The end customer can return the empty container at the shop, it gets sent back to the factory where they are washed and refilled. Then you can skip the extra refill step at the shop completely.

That said reusable packaging isn’t always going to be more environmentally friendly or cheaper. Transport and cleaning isn’t free, neither is the extra labor involved.

This is what Coca Cola used to do with glass bottles, but it cost them too much and that's why we have plastic bottles. All profit.
