Felix As Good As It Looks pouches 12 x 100g rolled back to £3 from £4.32.
Works out at 25p a pouch
I saw this in Asda at Charlton, London and all the adult food was marked up as £3 but the kitten food wasn't - it is online though so it may scan though at £3.
Not quite as good as the Pets at Home offer (21p a pouch) below but still better than full price!http://www.hotukdeals.com/item/705144/felix-adult-pouch-as-good-as-it-loo
Not sure of expiry date as online it just says rollback rather than special offer.
