Shopping online is a great way to find items that are either hard to find or simply aren’t sold here in Australia, however you may find that many U.S based stores simply don’t offer International shipping.
 
A good way to get around this is to use an online service like ComGateway.com that can either make a purchase on your behalf, or set you up with a U.S postal address with redirection back to Australia.

Not only does this give you access to online shopping stores that simply wouldn’t deal with Australia, but also online auction from eBay sellers in the U.S.

With the stronger aussie dollar at the moment, shopping online from the U.S can be a good deal.  Check out www.comgateway.com for more info.
