If I know in advance that a seller uses Couriers Please I'll avoid dealing with them; sadly you often only find out when the dreaded yellow and red card appears.
Two recent examples - both times the courier rang my intercom but walked away within 20 seconds and had left within the two minutes it takes me to get to the building entry. The tracking website form doesn't accept the card number for redelivery, so now I have to hire a car to collect the parcels from their "pop shop" three kilometres away.
