Up until a few year ago the Royal Mail van driver who normally delivered larger items would also accept payment provided it was the correct amount as he could not give change. Parcel Force were still collecting payment at the door but their minimum charge of £13 for a Japanese CD made it uneconomic to use.
BTW I'm on your side have already alerted post office union activists as to what is happening in Holland. No offence intended but I suggest you start looking for an alternative occupation while there is still time.
