Advanced Shipping Rate Manager

After searching for quite a while and trying other shipping apps, I couldn't find any that would solve the complex shipping issues I was having with my Shopify store. ASM dealt with all these issues and more & Burt has been extremely helpful with his advice. The only issue I have had is that the weights & preset shipping fees are based around those found in the US (I'm in Australia) so a little bit tricky trying to convert those, but otherwise a fantastic service.
