'It is a powerful selling tool that SD has taken away. The only way out of it is to cancel all the orders, and then ask the customer to re-order in one go.'

Yes. SD has effectively taken away all the postal flexibility from the private seller. It just beggars belief that eBay has brought about a situation where we are now obliged to cancel, refund & relist items, in order to be able to offer combined postage.

Frustrating & awkward for sellers, confusing & irritating for buyers... 😬
