Cadbury Easter eggs have reduced in size by almost 10 per cent in the last three years.
The research found that consumers are getting around 25 grams less chocolate per box.
Global supplies issues, the pandemic and the war in Ukraine have contributed to price hikes in Cocoa and sugar.
Consumer Journalist Siobhan Maguire explains how confectionary retailers are slowly reducing the size of products:
"Where there is a lot of packaging used in the product., it's easier for retailers sometimes to downsize the product itself, than make the packaging look any less smaller, and what that means is that the Easter egg that you would have bought two years ago is 10% smaller than the Easter egg you will get this year from that very same chocolate manufacturer."
