Competitions and expectations of prize delivery

If you receive a notification that you are a winner of a competition you entered, saying “Your prize will be delivered to you shortly”; what timespan do you take shortly to mean?  Days?  Weeks?  Months?  I think it would vary depending on the logistics of prize delivery but can’t really see anything over six weeks or so as reasonable.

I received such a notification almost three months ago and have not yet seen any sign of my prize.  Sadly this is pretty much par for the course with this particular competition.  I have been a winner three times before and on each occasion it took months to receive my prize; in one case almost nine months.  It’s disappointing, and gives the impression that one’s entries aren’t really appreciated.
