There are a lot of different fan-favourites to choose from and while some may not be an entire £6 saving - I paid £3 for the Lego Friends annual before Christmas - it's still a pretty decent saving.
Included in the offer are such titles as Lego: Legends of Chima, or Moshi Monsters. There's also WWE, Star Wars and Angry Birds.
Disney gets a good look-in with Disney Fairies, Monsters University, Princesses and even a Pixar Annual.
There are plenty more, all with puzzles, stories and adventures. Some also come with a no under 3's warning, so just check the individual ones before you make your purchase.
