I'm probably looking at something impossible but here is the scenario:
I am building a website where there are a multitude of items for sale from small cards to large items such as mugs, etc. I want to be able to set up postal charges in the UK, Europe and USA for these items. On the other sites I have used eCart I have been able to set the shopping up as to the number of items as all the items are of the same type (posters, programs, etc) However, due to the differing in nature of the items on this site I am wondering what the best way of setting this up would be. Would it be weight? If so, is that done through the configuration process?
