Jason I totally explained myself wrong. The idea that I want to accomplish is having Standard, Recorded and Special Delivery all stored in the database, These are used for UK shipping rates based on weight also International is based on Standard shipping/weight. So for UK customers they can chose recorded or special delivery (standard delivery will ONLY be used for small items like gift vouchers or the cheapest items). Everything works in terms of the correct delivery price being calculated depending on country and weight...but it looks a bit messy if in the select box "standard delivery" is showing as an option when it wont apply to items thats shouldnt be send using that delivery method.
on a side note, I just realised the customer wont know they delivery charge until the checkout page posts to paypal. is there a way of displaying the delivery cost based on country and weight on the same page of the select boxes that the customer needs to select for shipping to be calculated?
