Aside from the audio-visual content that Prime membership gains (I haven't even looked into it, so don't know what you get), I still find the purchasing benefits worth it for me. After all, their prices take into account the cost of shipping, so why not get as much as possible as "free shipping" so that I'm not paying extra shipping.... and if something is released in America earlier than here and Amazon Australia gives us access to it, it will also give free shipping if Amazon is the seller.

The delays are still very annoying, and I hate having to see others with new toys a month or two before me, but I just can't afford to buy from the first-release sources if the cheaper option ends up being Amazon. (a bit like BigW, who usually gets their stock last because they often negotiate a cheaper price from their suppliers and have to wait longer for it)
