Dissapointed

I bought few groceries at Woolworths Basonnia on Saturday, today I open a pack on simba chips(hand cooked crisps) and they are so stale decided to check the as expiry date:06.03.2022 and sell by it's the 03.03.2022 meaning they where supposed to be removed from the shelf already. Am actually dissapointed and wasted my money because now I have to throw them away
