Available from July, the three-month long promotion will be running across Cadbury Twirl, Cadbury Boost, Cadbury Wispa, Cadbury Wispa Gold, Cadbury Double Decker and Cadbury Crunchie, featuring a “two for £1.10 or 60p” flash on-pack.
The brand said price-marked packs offer a number of advantages for retailers, generating a “perception of improved value and trust” from shoppers.
It said nearly one-third of all bars sold in independent and symbol stores are Cadbury bars, selling on average at a rate of four units per second in the channel.
