Unfortunately it is not possible to list items on eBay via our platform, with "Local Pickup Only" as the postage service.
Omnivore only supports the listing of products on eBay with the "Immediate Payment Required" option enabled.
(This is to ensure that sellers using the platform only receive fully paid orders, rather than having to chase full or part payment of an order post transaction, as it can cause multiple issues/overheads for sellers when selling in multiple channels.)
For this reason, it is not possible to list items on eBay via our platform with a "Local pickup only", as with "Immediate Payment Required" enabled, it is an eBay requirement that shipping costs are specified when you list an item.
