Today I've had my third recent purchase cancelled by the seller. Mysteriously, the (low value) item they had listed for sale is no longer available from the supplier and they can't guarantee when it will be so they've offered a refund. I understood it was against ebay rules to offer an item you don't actually have and I've never experienced it before now. I'm filtering for UK sellers only to avoid post Brexit import issues so I'm confused - anyone else had the same issue?
