The wife did a click and collect order from woolworth and as part of that she had 1kg chicken breast but they gave us 1.33kg and she says we wont get charged extra for this, we had a few other deli items and same deal, athough they were pretty close to the mark on the other items like sliced cheese. She has checked the receipt and they haven't charged us more.
Seems like a good deal (assuming my wife is correct)
Yep, has been a known thing ever since WW started doing home delivery
Coles however charges as its packed, meaning if they add extra you get charged for it :/
