Peg, are you talking about washing soda crystals? I had a really hard time finding them in Coles too, I eventually found them not near the washing powders, but on the bottom shelf near the pegs - although that was a while ago & my local Coles has rearranged stuff since then.

HTH
cheers for that, i'll have to have a really good look.

it would probably be easier if I knew what i was looking for, but as i've never seen a packet of washing soda its probably what is making it hard to find.
