Someone has bought several items and wants combined postage. Can't send payment details because ebay changed the postage method!!!!!!!!!!!!!!!!!!!!!!!!!!! Another has bought several...some with my normal Royal Mail postage and the others were changed by ebay to the simple postage. They want combined postage. What do I do? This whole system is absolutely rubbish. I note on another post, someone sold several items and had the same problem and the buyer promptly cancelled the order for all the items. I am sick to death of this pathetic new system. Someone please help me. Stress levels through the roof.
