ebay is a pain in the ass, to be honest. Shipping outside the USA is also a MAJOR pain in the ass. Especially if they are in canada. They always want you to fill out forms saying its a gift, so they don't have to pay taxes on it. Then you piss them off if you refuse, then they neg you. And yes, ebay is very pro buyer. Sellers, they don't give a damn about. Which is why I don't sell on CL anymore. I'd rather sell on craigslist or consign it to a shop or even on offer up.
Agree on the bias, I just described that. But it must be a while since you sold, 'cuz you don't have to deal with the customs forms or international freight any more. All you do is send it to eBay in Erlanger Kentucky (suburb of Cincinnati). They handle all the customs and charges for shipping to wherever. All the buyer needs is the same shipping you'd use to anywhere else in the US and presto, it goes to Australia. eBay charges the buyer separately for all that and we sellers never even see it. Truly hassle-free.
