Question about mailing in subscription

[Private Burns]

I have recently mailed in a check to start subscribing to AH and I'm wondering at what time if i so choose to resubscribe, should i send in my next check?

Consider sending in a bigger chunk. I think (call HTC to verify) that if you send in a 5 months in advance you get the 6th month free.

A quick call to HTC would let you know when the check would have to arrive by.

You get monthly emails from HTC telling you what your account balance is.  When your account dips into the negative you get a pop up screen when you log into the game.  At that time I think you have about a week before your account will get put on hold pending payment.
