Yep. The same thing happened with LLBean. They used to offer lifetime returns/warranty replacement on all items, which worked when people acted in good faith.

Yep. The same thing happened with LLBean. They used to offer lifetime returns/warranty replacement on all items, which worked when people acted in good faith. After many decades of this policy, a gray market of used LLBean items emerged, people would buy multi-decade-old used LLBean items, then "return" them as worn out for a new one or even a full refund. It became a whole cottage industry, and they now have a one-year limit on their any-reason return policy. People suck, especially when they are disconnected from the human side of business.
