Went into my local Sainsburys (Wigan) tonight and they had these twin pack of the smaller Avent bottles for £1. They are around £8-£10 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.
With a two-hole Slow Flow teat, ideal for newborns or breastfed babies of all ages
Two-piece anti-colic system reduces colic and fussing
Encourages proper latch-on and feeding
Extra-soft, naturally shaped silicone teat is odourless and taste-free
Obviously the teats are interchangeable and Sainsburys are currently selling the packs of teats for £1 also (see my other deal).
