Here's a real world quandary. At TerraCycle we recently launched a line of ultimate eco-friendly cleaners. Their efficacy is great (same or even better in some cases than the synthetics). They are packaged in used soda bottles, with end run triggers, and moreover, they retail at a strong price ($2.99 for a 1L bottle). We've gained some fantastic distribution from Office Max to Target and have been happy with the sell through.
