Sorry if this has been posted before....
Same as the creme egg deal but for the Mars eggs and Galaxy eggs @ 20p per egg.
Found this in the Leigh Park store in Havant - would guess it's nationwide but not sure as the creme egg deal doesn't appear to be. Pot luck I guess :o)
Will post receipt in thread (if I can figure out how to do it!) Enjoy chocolate fiends! :o)
