You have to be kidding, there is no such thing as a full sized Snickers bar any longer. Squeeze a 4 pack sometime and you will see it is full of trapped air. These things and the so called full sized bars Snickers are now so small now that I refused to be ripped off by them and have given up buying them despite loving them when they were priced and sized properly a few years ago. 50p for four sounds about right and possibly a fair value. So a good find if these are what you like.
