Re: Qantas taking Qantas Club vouchers off eBay!
As a seller, I *despise* eBay and PayPal. They end up taking nearly 15% of my sale and if I have the audacity to say 'direct deposit preferred' they will de-list my item. Likewise you're not allowed to surcharge for PayPal. People then up the shipping costs, and eBay have been known to come down on the people who sell an item cheap and then have expensive shipping (shipping and sale are different in PayPal).
As a buyer, i'll use it to get sample pricing, and shop direct with the merchant (many online eBay regulars are from stores, so i'll buy direct from them for the same price; they make more, it costs me nothing, and i'm happy).
eBay has its uses, but it's making money for jam pretty much. I've often considered starting up a competitor to them, but with the clout they have, they'll either put you out of business or buy you for few bucks (not millions either).
