Who wants to save, should definitely take up this edition - all DLCs and the main game, for any 30 - only the DLCs cost more if you want them to purchase individually.
Add to that a nice map of the game world, a brief description of the DLC and a booklet.
The installation process of the bonus content is the way in English language, which is, however, kept simple and should be understood with basic knowledge.
Who owns the download edition of Skyrim and is not sure if the download CD works and he needs to play with the disc, I can calm down - it is sufficient to install the DLC once via CD and you can watch the disc the Bosusinhalten throw away or do what you just comes to mind. The game disc does not require you (if you have the download version of Skyrim) and they can thus be supplied to sell..
