46p each everywhere, forget the multipacks and 2 for 80p deals this is about the price for one Creme Egg. Seems to me Cadbury must be putting pressure on retailers not to sell for less than 46p. Someone who used to work for Woolworths mentioned last week that Cadburys mess with supply to shops that sell at discounted rates.
If you go to the OFT website you can email a complaint about this anti-competitive price fixing practice: http://www.oft.gov.uk/contactus#named3
The 2 for 80p deal seems to be very common as well, I bet they're in on that too.
