It is the choccy promotion that has caused a frantic Willy Wonka-like search for Creme Eggs.
Cadbury’s are offering €1,000 if you find you have picked up a rare white version of the treat.
Last week the company revealed they had 350 to 400 white chocolate eggs hidden in normal Creme Egg wrappers.

But it has triggered mayhem after staff in supermarkets were accused of opening the wrappers to see if they had won.
However, it seems there is an easy way to find out if you are onto a winner.
According to Metro the list, on the back of every Creme Egg, usually includes milk chocolate as an ingredient.
Only the special version replaces the milk chocolate with white chocolate.
So remember to always read the label.
