I am not trying to tell you what to do, but We talked to our pediatrician about generic vs name brand formula and she told us formula is so heavily regulated and the generic ones (at least in the US)made by similac, nestle, or enfamil that the generic is as good as the name brand..
I am sorry I don't have any- but I do know you can sometimes find them on diaperswappers. There always seem to be people offering them up!
