You know how at the supermarket there are the big and the smaller supermarket trolleys and once you put your shopping away in your car if it is a big trolley you put it with the big trolleys and if it is a smaller trolley you put it back with the smaller trolleys in the carpark (not rocket science).

The numpties selling at 1.4c are the same people who will put the bigger trolley with the smaller trolleys and vice versa so the poor trolley collector (who is paid pittance) has to sort it all out.
