Inconsistencies with Online and instore promotions

Good day

I would like to enquire as to why there are inconsistencies between your online promotions and your instore promotions?

Considering the pandemic i try to avoid going out unnecessarily. ..

So when I saw your pamphlet for the week i had to make a trip to the store as promo items where not available online .I also saw a kettle on promo online and opted to purchase it in store whilst I was doing my groceries .However after paying for my items I was told that online promotions and Instore promotions differ.I was charged full price for the kettle.

As mentioned I am trying to avoid going out unnecessarily, so I am not going to now go back to the store .... waste time and fuel to return this item and purchase it again online.

What happened to convenience shopping .Currently as it stands I need to purchase some items online and then go in store to purchase other items on promo.

What is the logic behind you not offering all promos both online and instore? Woolworths does it why cant you?
