When I worked on REACH toothbrushes, the brand faced an ongoing dilemma - few people changed their brush as prescribed (4x per year and after an illness). The brand team obsessed about and implemented plans to change consumer behavior using education, sampling, product innovation and advertising. The price range at the time was between $1.99 and $3.29. Nothing worked.
I was at a meeting and suggested that since people were not changing behavior, maybe we should introduce a higher priced toothbrush - after all, $5.00 is not that much money and if customers were only going to buy 2.235 toothbrushes per year, might as well be a higher priced version. It was just a random comment, I had no data and no deeply held conviction about my suggestion. My suggestion was denounced as unviable as it was not aligned with the price elasticity study that had been conducted.
A few months later ORAL B, the market leader, introduced the first $5.00 manual toothbrush (the Cross-Action). It had a cool-looking design which gave it a high tech image. It was a huge hit.
I'm sure I'm the only one that remembers this story and remembers it that way but that is the way it happened.
The point - you can either try to change behavior (very, very hard) or accept it and leverage it (not easy but doable) - your choice.
