a customer needs to include transport fee in the product price whithoug showing transport fee in detail.
this is the request
1 - customer enters in the shop and choose the zone (eg: spain)
2 - the system get the transport fee for spain (transport fee is fixed for each country)
3 - the customer enters in the shop watching products and prices where prices are product price+transport fee - this means that he sees immediatelly the full cost of a product
4 - checkout is ordinary without transport fees already part of the product price.
we need an estimate (price and devel time) for this customization
