Their refund policy seems to say no…
“
Ongoing Subscription and Cancellation. Your subscription will continue in effect on a month-to-month or year-to-year basis unless and until you cancel your subscription or the account or service is otherwise suspended or discontinued pursuant to these Terms. You must cancel your subscription before your monthly or yearly renewal date in order to avoid the next billing (each Monthly Period or Yearly Period). We will bill the monthly or yearly subscription fee plus any applicable taxes to the Payment Method you provide to us during registration (or to a different Payment Method if you change your account information).
If you cancel your subscription, cancellation will be effective at the end of the current Monthly Period or Yearly Period. This means that you will have continued access to your subscription for the remainder of that period, but you will not receive a refund.”
I’m gonna wait till before the next home game to bang the monthly fee for two months - that should cover me to the end of the regular season.
