IMO, Aldi is leading the charge with the price hikes, followed by Colesworth, and lastly, IGA.
For example, the price of Aldi powdered milk went from $5 last year to $7, now $10!
Baked beans went from 65c to $1 at all the supermarkets expect for IGA (as of late march).
Everytime I go to Aldi (about once a month) I always get a shock when I see the significant price increases on products I have been purchasing for years.
It's good to see Coles has the "price lock" guarantee. It gives the consumer more certainty about prices in an inflationary market.
I have tried to stock up on non-perishables as much as possible but there are limits to how much one can purchase, store, and consume.
I was always under the general feel that apart from specials, IGA was consistently more expensive than Colesworth?
