Acorn offers an impressive selection of British tv series but only the current season is included in your subscription. Earlier seasons are available only through iTunes at $2.99 an episode or $14.99 per season, as we discovered in the series "Vera". The same proved to be true for other offerings. Decided to cancel after first viewing session and truly disappointed that iTunes is in on the deal. Now hoping the cancellation will actually go through without continued billing to my credit card, as has apparently happened with many other disappointed customers.
