Yeah but it locks you in. Another example of how the hysteria around climate change is exploited by companies for profit. Once you buy Tide washing liquid in a returnable container there's a higher cost barrier switching to another brand. Unless they standardize the packaging this is a pure profit move.

On a broader note I often wonder if all the talk about climate change and plastics is not fueled by corporations ready to exploit it. I just cannot believe that a topic can suddenly become so big without an agenda behind it.
