On my store items I have always had free postage, I have always offerd an express option at a price, and I have no problem offering refunds for not as described goods up to 30 days, Paypal will force me to accept them up to 45 days anyway.

On my auction ids I will never make PS status anyway so I will continue to charge for postage in th same way I always have.

I don' usually sll while I am back here in the UK but so many Aus sellers are doing so much complaining that if even 10% of them do actulally stop selling it may be worth my while even with having to post from the UK.
