Boots have got an offer where you get baby milk at a discounted price for instance Cow and gate number 3 is £5.28 (usual price is £6.28).
but if you spend £10 on baby essentials (the milk comes under this) then you get 200 boots advantage points.
also go through quidco to get more savings and make sure to take it over £45 to get free delivery!
(i think the sma offer is two tins for £10)
