Hi, I am using this addon to calculate the postage cost for any orders ( http://addons.oscommerce.com/info/4473/v,22 ), although it is for vers.2.2 it seems to work very well in my vers.2.3.3. My problem is that all my items come under the small packet rate except one, it is 12" x 9" x 9" box which weights only 380grams. Is it possible to add this one item as a separate option, I would use Hermes as a carrier. Regards, Graham
