in Europe a supermarket buys the products; usually it will pay in 90/120/180 days and it has the option to return unsold items and will have advertising agreements for better/larger shelves, but everything is in the store is own by the store
This is not universally true. Slotting fees and shelf rental agreements are a thing in Europe, just like they are in the US.
Having a Nespresso concession stand that sells stuff on their own, doesn't change the fact that the retail side of the operation is inherently the owner of the products.
