I've used eBay for a very long time. Since it was first launched in Australia, I think. They had got the balance between buyers and sellers right. Recent changes of policy have forced me to think about whether or not I'll use it in future. I've decided that I won't.
They now require that you offer Paypal as a payment option, and will soon make it the only payment option. Paypal is not a bank, so your money is not guaranteed against failure of the institution. Paypal's dispute resolution procedures are opaque and poorly-implemented. Getting Paypal to connect with your bank account is a tedious, multi-day process that often fails. I refuse to use Paypal.
The recent changes to the feedback system also, I believe, skew things in favour of sellers too far.
Online auctions are really useful ways to buy and sell stuff, and you can often pick up real bargains. Conversely, when selling some people will end up paying RRP or more for used goods, which makes it great if you're selling. Now to find an alternative venue.
Any suggestions? I've found OZtion a bit crap.
