If the shipping setup is not configured for orders over a certain number of items or if you have included fractions in your shipping table, the API will not know what to charge for shipping. On checkout, it will show $0 for shipping, and your customer will get the message, "Due to the size of your order, additional shipping rates will apply. We will contact you to advise you of the shipping rate."

For example, if you still need to set up shipping dimensions for each type of product you have (i.e., wine, spirits, beer, gifts, etc.), your orders will show this message. Remember, our default install includes sample dimensions for up to 12 bottles, so if you, for example, add up to 3 cases, anything over 12 wine items would generate this error. Or if you have more than one product type, such as gifts, and the customer adds one wine and one gift, it would also generate this error.

**Important: Use whole numbers only. Do not include fractions or decimals in your dimensions, or you will receive a shipping error, and your orders may not be charged for shipping.

Correct the initial shipping configuration for each product type.
