I have done some shopping with Aldi, and esp at Christmas when they have a lot of things that I like.
Having said that, I will never again buy anything that is electrical! from them.
They seem to have people returning a fair amount..
I like their meat, and a few items that I can not get at Coles and Woolies.
But, if I had to give up Aldi, I could no problem.
I like to keep my shopping to the other two for 90%, keeping it Australian as much as I can.
So now and then a little change, but I would like the two big ones to give a little more in variety.
