Disgusting expired goods sold...

This is the 3rd time that i have realised AFTER purchasing goods from Woolworths Food at Castlewalk that I have bought expired products. 1st time juice. 2nd time pork stirfry and tonight realised the slow cooked beef ravioli that I bought on 4 Aug already expired 13 July.... HOW is that still on shelf? I buy from Woolworths at least 4-5 times weekly. I'm rethinking that. This is unacceptable. I expect quality from Woolworths.... I don't keep slips for consumable purchases so I can't even take it back.
