4GB usb Flash drive in the shape of a soul stone and a diablo skull holder is easily 20 dollars. D2 and LoD still sell for 10-20 dollars from Blizzard (included on flash drive) WoW pet is about 10 dollars. You also get D3 dyes, wings, and SC2 portraits and decals. As well as the standard CE stuff in the form of Artbook, DVD/BLU-Ray behind the scenes, and soundtrack.
Not to mention if you have the WoW annual pass you get 4 free months of WoW game time for buying the CE. I'd say yes its worth it even if you aren't a Annual Pass member.
