Ebay shipping - Package Size Source in eBay Integration Posted July 6, 2017 · Report reply Option 'Package Size Source' appears only when ……. Never appears in m2e no matter what is selected. Not an option for ebay UK re m2e but is an option for UK re ebay themselves. Yes using shipping rate tables, but that is the original problem that the shipping rate tables are not applied to any item where the package type is “letter” so the extra carriage from ebay shipping rate table will never be added. Change it to “large Package” and all works OK. From M2e Support which does not help either. "You list items on the eBay site UK where such an option is not supported. For UK market place you can set the shipping type as Freight: Large Items in Shipping policy to ship large parcels." Doing this causes. 1, makes no difference to parcel type on ebay 2, removes size and weight options as well 3, causes an error and wont talk to eBay Am I missing something here ?
