Found in Asda Grantham near other feeding bottles but on end of aisle on metal rack. Got one for myself as the colour my world bottles tend to be dearer. Currently £19.59 for same at Amazon. Picked up the blue & green set. Not sure if the pink sets are available but worth a look. If you just want the standard version of these 260ml 6 pack bottles, they are £10.00 at Amazon.
