That might have nothing to do with postcodes or counties. The delivery
company depot is chosen for their convenience and they might use the
Stevenage one because it is bigger and has more capacity than their
Cambridge one, even if the later is nearer. The fact that you have to
travel further to collect a parcel doesn't bother them, you aren't even
their customer.
