Tazos In Walkers Crisps
Buying crisps you did not want for a plastic disc you did.
Looney Tunes and Pokémon discs given away in crisp packets, which drove sales to extraordinary levels.
Children bought multipacks and ate the crisps grudgingly. Some just took the tazo and left the crisps, which caused a certain amount of parental fury.
It is one of the most effective promotional mechanics ever run in British grocery.
