I like and use the GreenWorks line of products. However, I was disappointed to learn that when I run out of my favorite window cleaner or surface cleaner I have to purchase a new, non-concentrated "sprayer-top" bottle. What a waste of packaging for a brand that's being marketed as "green".......clearly, corporate greenwashing at its finest. The ultimate irony is that the non-"green" marketed Clorox brands such as 409 have been available in a refill bottle for as long as I can remember.
Simple solution: offer concentrated refills that consumers can purchase, reconstitute, and use in the sprayer-topped bottle they've already purchased. It saves you the cost of shipping more packaging, saves the consumer the cost of the more expensive sprayer-topped bottle (which I'm SURE you'd pass along in the form of a reduced cost per unit on the refill) and restores the brand's ability to market itself as "green" once again.
