Hi, Was just in Tesco, and saw these half price as an introductory offer, three kinds available:
Cadbury's Creme Egg - With Cadbury's Creme Egg mug, some Cadbury's Creme Eggs and a Cadbury's Easter egg
Cadbury's Mini Eggs - With Cadbury's Mini Eggs mug, a pack of Cadbury's Mini Eggs and a Cadbury's Easter egg
Cadbury's Dairy Milk - With Cadbury's Dairy Milk mug. 2 bars of Cadbury's Dairy Milk and a Cadbury's Easter Egg
These look like the medium sized eggs, the Mini eggs one has 216g on the side and the Dairy milk one has 214g on it, didn't check the Creme Egg one.
Also saw the Nestle versions (Kit Kat, Mint Aero and Toffe Crisp) there for £3.99 each which aren't on offer.
In-store and online (thanks to dontdothatagain)
Cheers for looking
