What are the products you only buy at Aldi or the other big shops? Reasons can be any, for me it is the quality/price criteria.
I only buy in Aldi : the mayonnaise (in the glass jar) as we don't like any other. The fruit no sugar chewing-gum (packs of 3); chocolate pillows; grated grana cheese. Raspberry and Apple cordial.
Woolworths: cooking salt with iodine. The diced home brand tomato cans are the best compared to other cheap ones, so I'll buy there when I can
Iga:macaroni black and gold (which I think is being discontinued)
Coles: no particular product.
