Not to sound rude or anything but she did say in bold 'Within Sydney' and also
might be able to ship out to people within australia via post but I gotta get paypal first~
It's very expensive to ship large items from Australia to the US because of Security tariffs(anything over 4 pounds it's the shipping cost plus $10) so she would loose out a lot if she didn't add shipping and if she did add shipping you would probably loose out too. So you would be better off to buy from somewhere else, just saying. it would be cheaper in the short term.
