I thought it was a good deal. Picked up 2 cadbury cream, 2 LIndor, 2 thorntons praline and 2 cadbury caramel eggs all for £2. (saved £2.16)
will post reciept once I get on to the scanner.
Dont know full list of what is available or what the potential savings could be, but the thorntons ones scanned at 57p each so could potentially save £1.28 so reduced by ~44%
