False Advertising

I am a woolies fan esp when it comes to their baby range and food range but sadly they have disappointed me. From last week when the sale started I tried looking for clothes for my baby girl. Then I added the clothes to my cart, I got a bit busy at work so I planned to check out later. Later on I went back to proceed with checking out then when I got to the cart the items cost less but when I get to the checkout screen it charges me normal price. I went out of the app and in again to make sure it’s not my phone and no it’s not. I checked the fine print and the only fine print relevant to shopping if the delivery fee is calculated at checkout screen not that they will give false prices to entice me then charge me a different price. The clothes are still on my cart and want them at the advertised price. Not deceive me to shop then charge me something else at checkout phase. I have pictures to prove this and it’s annoying
