This module is an amendment to the zones module to select a shipping cost dependent upon where in the UK (via postcode) the products are being shipped to.
I needed to develop this as my products are heavy and not subject to normal rates as in many cases they need to be palletised. Pallet rates vary depending on where in the country they are being shipped. HIghlands and Islands incur extra charges as well and this will prevent undercharging for a valid UK address.
I'm not a great expert on oscommerce so this will need to be modded to be a fully intergrateable module if anybody thinks it's worthwhile.
