Yes, it's ASP VB Script.
Is it possible to have an existing postage charge rule ignore certain products if they're in the cart? For example, if a particular product is in the cart we'd like it to be excluded from the postage calculation which is based on the cart sub-total. Hmm...even describing it out loud like that makes it sound impossible.
We're having a real nightmare trying to implement these two different postage scales, mainly because we don't quite understand how to, and certainly aren't confident about how to, implement the custom shipping rules and how to trigger them.
Would appreciate any advice you could offer.
