I need some Html or script for my Ebay template which calculates the postage cost for that particular item based on the weight of the shipping weight of the item being sold. I have the price tables in csv form already but need the html code to add to both the template and one of my store pages. I need this like yesterday! I am sure this is a fairly straightforward thing to do.
The prices are based on Royal Mail prices (Airsure, International Signed For and Special Delivery) to the UK and abroad.
