Because it’s shoes , the sf courier come and insisted an extra outer box must be added to avoid damage in transit (even though I already had a box) the courier kept explaining this while we were in the same life. I agreed because I had no choice because the courier came while I was going out to pick up my baby . Btw, if cancel pickup buyer later need to pay higher SF fee is ask SF come again later . If buyer want to skip the “add box” requirement she should heads up in advance.
