Back home if I ran out of dish soap, shampoo, or the like, I would just buy another bottle. In Japan I can do the same but more often than not I do this:
I save my dispenser and buy a refill. Refills are shelved next to their bottled counterparts and priced typically a ¥100 or so cheaper. It just makes sense - I have both the satisfaction of using less plastic AND I saving money. It also seems like a win-win situation for the manufacturer which makes me wonder why this idea hasn't taken off in the States? Do product refills appear in other parts of the world? Do tell.
Here are a couple of store shots that shows other examples of refills, toilet bowl cleaner, fabric softner, and shampoos.
