Some of the other posts in here have touched on the topic of product dimensions but I haven't found an answer that is clear.

I've just setup my online store at geekworkz.com.au/store and it's all come together really well. But I noticed with no place to enter a products dimensions the ozpost module is using the default size to generate a quote. The problem is I have different sized products including televisions which obviously are too large to send by Austpost so I am using Transdirect which doing the quote on their site would cost approx. $134 in the sample I used. However the ozpost module only quotes $34ish.

I tried adding in the numinix addon but that screwed my store completely. So I'm at a loss after spending all day on this. I cannot find a simple way to add dimensions (WxLxH) that ozpost can use. Someone please help point me in the right direction.

Thanks,
Troy
