Reading the post I worry that people will be confused and think they need to buy by June 30th even if they've started a trial on or before June 15th. I think the need for clarity here is important. @ChadMalchow I know this conflicts with your previous feedback, but I really don't want prospective customers confused by a convoluted post here.
