Went into my local Sainsburys (Wigan) tonight and they had these packs of 2 teats for £1 a pack. They are around £3-£4 everywhere else.
I asked and its a national deal to get rid of all old Avent packaging (they must be bringing in new ones). HOWEVER people have been listing that it is definatley not in their stores and all they are getting is 1/3 off, so apologies if your local store doesnt have them at this price. Wigan definatley does, hope this helps someone.
