I have a membership to a workout studio that is pretty pricey ($150). I recently found out that I will be moving sooner than expected, and won't be able to utilize the studio for the next month. They have a 15 day cancellation policy, so under that, I am still forced to pay the $150, even if I have no use for it. Is there anyway to stop this charge before it happens? Or am I forced to eat the $150?
