We use ChitChat's International , it's cheap and reasonably fast to Europe, but very slow to Australia and NZ. I select "Economy Int'l Shipping" and make prominent note on top of description that Worldwide shipping takes 2-6wks.
NZ buyer opens case after 5wks. When I ask why he opened early, he shows me "Sale date: 04/24/14 Tracking number: -- Estimated Delivery: Tue. May. 6 - Fri. May. 23".
Ebay is promising housenumber transit time on my behalf without giving me chance to change it and I am supposed to have an obligation. The guy demands a refund early based on Ebay's promise, Ebay should refund from their own pocket.
