What if I held onto the reply-paid envelope for, say, six months, and sent it back to them then? There must be a term limit on the parties claiming postage back from the taxpayer, but that reply-paid envelope will probably work for years.
@futzle Hmm, well if that prepaid account is still active they'll probably be able to claim it somehow. If not then it'll be shut down and Auspost will wear the cost.
