Cannot agree more. EBAY are destroying the platform. I wonder if they no longer want private sellers. You can't combine multiple purchases, which is a key selling tool. You can't buy expedited delivery for special occaisions like a wedding or birthday present. You can't just deliver something when you realise it was bought by a neighbour - plus their lousy AI system gets the postage label wrong. You can't cancel them - you can't buy your own correct label and enter the correct tracking number. Or to put it simply it is impossible to know what the best shipping method, and rate, is until all the stuff is packed and you know what the customer wants. 

Add this to there crackpot buyers fee EBAY is becoming impossible to use. But they do not seem to care, so that is why I think they just do not want private sellers anymore.
