Two things, start a new thread instead if dragging up old ones, and utilise the spell check feature. You message is hard to read.

Regarding your price, if you look at the listing, it will say the conversion is approximate. Many things can alter it, including fluctuating exhange rates. Also, when you go to pay, PayPal is converting your money into USD, which is not a free service. You are being billed for them to provide that service. Yes, you could get your bank to do it, but you'd be paying double what PayPal charge. Contacting the ACCC is going to achieve nothing, because neither PayPal, or eBay have done anything wrong. It's all in the terms and conditions that you agreed to when you started using the site.

I am looking forward to seeing your reaction when you discover the customs charges on that purchase! Please start a new thread when you come back to complain about that. It will be worth seeing.
