Our YTO and STO couriers will come downstairs and call you, telling you that your courier has arrived. Please go downstairs to pick up the courier. Then you can just go downstairs to find him.
When you pick it up, you can first check whether the outer packaging is damaged before signing. I have never encountered anyone who signs first and then inspects the goods. Generally, if there is no problem with the outer packaging, then the contents inside will be fine, too. Open it in front of the courier and check if there are any problems before signing for it
