A. Before adding items to your cart, take note of the prices and any ongoing promotions. If you notice a price change after adding an item to your cart, try refreshing the app or logging out and back in to see if the price reverts to the original. Additionally, check the app's terms regarding price changes, as they may have specific policies in place.

B. Consider taking a screenshot of the item with its price before adding it to your cart. If the price changes, you can use this screenshot to reference the original price when contacting customer service, if needed.
