Toblerone are giving away 20,000 free samples of Tobelle here.
Tobelle is "a tantalisingly slender triangle of Toblerone".
I personally would prefer a tantalisingly big, fat chunk of Toblerone - but what the hell, it's free!
If you are lucky enough to be selected, the sample goes to your significant other so you need to get to the post first ;)
Enter before 1st January 2010. Good luck!
