I have noticed that some cleaning products, "POTZ" , the refill does not exist, and if there is one it is cumbersome.
Why not sell the concentrated refill, i.e., that must be diluted with water.
By doing so we have significant savings:
1. less consumption of materials in production
2. savings in packaging disposal
3. less weight = less fuel consumption (Migros trucks and motor vehicles) to transport these
3. smaller footprint
