yeah like the other girls have said you don't get formula milk on offer...
Even the sainsburys add that was on for the 1/3 off baby products stated at the bottom *Excludes formlua....
Though I don't see why they shouldn't do it on offer... yes it is an essential for those who bottle feed but so are nappies, wipes, bottles etc & they are always on the offers either at Sainsburys, Tescos or Boots etc...
I was even looking in a wholesaler to see if they were any cheaper but they werent & all their other products are cheaper as they sell to the trade who then sell to the public...
