An item remains reserved for 15 minutes when you place it in your shopping basket. The fifteen-minute period restarts for the entire shopping basket each time you add a new item. So as long as you are actively shopping, you don’t need to worry that the last items will be sold out. Please note that if there is no activity in the shopping basket for 15 minutes, the reservation expires and the items become available again for other online shoppers. If an item is sold out in the meantime, it is automatically removed from your shopping basket.
