The number table shipping module by ZIP code zone allows you to specify different shipping charges based on the method of shipping AND the number of items AND the ZIP code the item is being shipped to. This module evaluates the "ship to" ZIP code and displays its methods and charges applicable to the destination. This prevents customers from selecting its methods with lower shipping charges which may not be applicable for them. Great for local shipping charges. Not compatible with the current google checkout module as that module does not use the customer's address to select the shipping methods available.
The number of items are setup by range groups, ie. from quantity X to quantity Y, the charge is Z. Multiple range groups can be established for each
method of shipment and each ZIP code zone. A ZIP code zone can include one or more ZIP codes. As a wildcard, you can charge shipping to all ZIP codes not already placed in a zone rather than placing every ZIP code in one of the zones.
You can exclude specific product codes from the calculation of the number of items. If you do this, you should have a range of 0 to 0 so that if the customer only orders exempted products, Merchant will still be able to display
a valid shipping option, e.g. Free.
