Shipping categories, methods and zones

This is a bit hard to explain but...

A product belongs_to a shipping_category Shipping_categories have_many shipping_rates shipping_rates belong_to shipping_method_id

So effectively a shipping_category will have_many shipping_methods, through shipping_rates

shipping_category

 has_many shipping_methods, :through => :shipping_rates

So now There needs to be a shipping_method for every shipping_zone you ship to.

So for example:

Lets say you have 2 shipping zones: Canada and USA

Now you have a desk that you are selling on your site. The desk might have a shipping_category of "large furniture".

The shipping_category now must have at least 2 shipping_methods (hence also 2 shipping_rates)

• one shipping_method must have shipping_zone === CANADA
• one shipping_method must have shipping_zone === USA

Most likely you will have a few more shipping_methods for each shipping_zone.

This is actually something I'll try to validate before you can activate a product soon.
