From Freagol:
I’ve bought 2 boxes of “Crunch” cereals Wednesday in Auchan Luxemburg (but it is french packaging so I suppose it will be available soon in France too). They features a bonus : 2 different CD-rom about the film, including letterheads, screensavers, wallpapers… 1 CD for one point (i.e. one box), 2 for 2 points (i.e. for 2 boxes). I’ll send scans of the box as soon as possible.
