Replying to Suspicious Reciept/Refund

Randomly in the mail today I recieved a check for 14.97$ from Time Inc. Shared Services in Florida.
The reason I think it has something to do with skiing is because above the line that has the amount, there is a line htat says "FOR SKI (then my account #) then its says "Reason: Cancel"

Now I know for a fact that i have not canceled any of my subscriptions for any ski magazines so I am wondering if any of you might no what it is from?
