I don't buy J & J products. ( no way! )
I don't buy Nestle products as I read about how they endorse the use of formula to poor countries etc hence women over there aren't BF'ing and instead buying formula.

I stay away from Aspartame (diet drinks)

I try and buy Australian Made even if it means I pay more.

I always buy enviro cleaners over nasty chemical cleaners!!

Um there is heaps more but I can't think of them right now.....
I'm pretty much the same - well and truly making an effort to avoid Nestle!

Never buy soda drinks, I buy Australian made as much as possible, tho I've seen the odd American creep in.

The only thing I wish I could avoid is Domestos, I can't handle the smell, it makes me sick but its the one thing that I can't seem to keep out of the trolley, speaking of which is hardly ever full as I try to buy my stuff from the local smaller shops.
