The way woolies do letterboxing, I don't think they can have differential pricing within the one urban area. The specials are not specific to a store normally. (could be wrong)I havent compared them but are Woolies Metros like this size generally more expensive than normal Woolies?
They do specific exclusions for rural-and-remote around things. I think they were somewhat obliged to do flat pricing to avoid regulatory oversight, they could do predatory pricing to try and drive smaller/independent outlets to the wall.
