I just remembered Skydivers ... salt and vinegar puffy crisps shaped like parachutists.
I don't think I was remembering Discos earlier I think I was remembering Roysters ...
I love wotsits. They ones M&S do are really nice.
Do you remember the M&S snacks which were puffy like Wotsits but round and they were hamburger flavour? I don't know if they still make them but they were gorgeous. They had a red and blue, stars and stripes type packet.
