Just been in my local B&M's in Prescot and seen these on the shelf. Asked the lady how much they were as there was no price. Also asked her if they should be in other stores and she said yes!! I have never seen these in a uk store before (Even in an american candy store in Wales) They are £2.99 on amazon per box.
I must admit, I hate these as I don't like peanut butter... But my fiance loves them!!
