Apple's iTunes has long featured a "Complete My Album" option, letting users who've bought individual songs from an album to buy the remaining tracks at a knock-down price. TV fans haven't had the same flexibility – until now.
Cupertino's added a "Complete My Season Pass" feature to iTunes – view an iTunes store page for a TV show (at the moment it only applies to recent seasons), and the Season Pass purchase price will be reduced to take account of your previous single-episode purchases.
Sadly, it doesn't seem to be working in the UK at the moment – we've just tried to buy one episode of Doctor Who's most recent series and then complete the season, and iTunes isn't playing ball.
Hopefully UK users will get this feature soon – we could do with saving a few pennies in the post-Christmas period.
