The bottom of the post mentioned that sales have increased by 40% with the new design. It will probably take some time to know if that sticks, but it seems like it works from that point of view, even if it was maybe overpriced.
The 40% increase is ~$18k a month based on the numbers in the article. That means that redesign pays for itself in three months. That's the type of "regret" that I want.
