I sold an item which I dispatched on the 29th Second Class. Obviously there have been strike days and a weekend, but the buyer is now chasing because the item hasn't arrived. Ebay's own estimate is for this to arrive between the 10th and 13th.
I so rarely sell on there because it's always a flipping nightmare.
Anyway, basically I'm not sure what the process is here. Does the buyer have to wait for that Ebay date to pass before raising it as undelivered or can they do it sooner.
Obviously with the way the RM is at the moment it could be held up. (My DH is receiving First Class parcels a week after they were posted!)
