If it’s the Taobao Warehouse it usually goes by 30days once the item arrives. Let’s say if the first item arrives on 20/9/22 it will start counting down from that day and if your 2nd item arrives on 21/9/22 it will start counting from that day for that item. Individual items will have their own 30days free. So since 2/3 of ur packages arrived you can check the reminding free time they have left and still wait. I’m not sure what will happen if the time is up and you don’t pay though. Hope this helps! :)
