How to use Coinstar for free?

I'm curious to know, is it actually possible to use Coinstar for free? I've heard rumors about people finding ways to bypass the fees, but I'm not sure how legitimate those methods are. Could you please explain the steps one could take to use Coinstar's services without having to pay any fees? I'd appreciate any tips or tricks you might have, as well as any potential drawbacks or limitations I should be aware of. Thank you for your time and expertise on this matter.
