Amazon UK have How To Train Your Dragon on DVD going cheap. If you include it in within a Super Saver delivery (which is the way to go) it is only $9. It could be the small purchase to bounce you up into free shipping if you are buying something else.
This will be region 2, so you'll need a multi region player.

Keepa.
is that you standard reply for any DVD or Blu Ray post these days? It's getting tired dude. LOL.
nope… i borrowed this one a month ago from my local library…
it's free and you get to keep it for 3 weeks… don't know why anybody would want to see it more than a couple of times, but you can always re borrow it and save yourself $9 to spend on other bargains….
…like Dr Seuss apps. Woah, like totally amazing man!
OK, we get it. You go to the library. It's free. You prefer that. But not everyone does. There is a price attached though: you are getting filthy germs from all the grimy used discs! Who knows WHERE THEY'VE BEEN! Ewwwww.
:D
You don't have a DVD collection?
$15.98 if you don't have a multi region DVD player:

Easily one of the best CGI "children's" movies I've seen in a long time.
my local council library has this for free…
