If your customer are receiving an error messages similar to these at the checkout:

Shipping country: Unable to calculate shipping charges, the weight/value of the items in your cart may exceed the configured amount for the country you are shipping to.
Please contact the store owner for further assistance.

Shipping state: Unable to calculate shipping charges, the weight/value of the items in your cart may exceed the configured amount for the country you are shipping to.
Please contact the store owner for further assistance.


This is usually due to one of the following reasons:

  1. If you are using Weight-based shipping, ALL your products and their corresponding product variations MUST HAVE a weight value assigned. Without these, the checkout is not able to correctly calculate and assign an appropriate shipping charge to total combined weight of orders going through your checkout, thus the error message you reported. Please add a weight value to each product variation if you wish to continue using Weight-based shipping.

  2. 2.1: Start your pricing ranges from 0.00. This helps to ensure there are no gaps in your pricing - now or in future. For instance, you have USPS Priority Mail From $ 5.25 → To $15.25 You charge: $ 6.50 I would recommend changing this to: USPS Priority Mail From $ 0.00 → To $15.25 You charge: $ 6.50 2.2: Ensure your shipping tarrif ranges cover at least the value of more than 1 typical product. The vast majority of your products cost $ 25 and above but your current shipping tarriff only covers up to $15.25. Please add more ranges to cover higher value orders. e.g. USPS Priority Mail From $ 0.00 → To $ 15.25 You charge: $ 6.50 USPS Priority Mail From $ 15.25 → To $ 500.00 You charge: $ 12.50 USPS Priority Mail From $ 500.00 → To $ 2000.25 You charge: $ 17.50 Alternatively, if you trying to set a fixed shipping charge for all orders, then you can simply increase the limit of your current tarrif to cover higher value orders. e.g. USPS Priority Mail From $ 0.00 → To $ 2000.25 You charge: $ 6.50 2.3: Ensure your shipping tarrif ranges cover up to a minimum of 3-4 times the typical order values you would expect through your checkout. Assuming your typical maximum order value is "$ 500 to $ 600", then I would recommend that your shipping tarrif covers up to 1500 - 2000 dollars. Please see 2.3 above for more details. 2.4: Ensure there are no gaps between your different ranges by overlapping the end of one range with the begining of the next e.g. USPS Priority Mail From $ 0.00 → To $ 15.25 You charge: $ 6.50 USPS Priority Mail From $ 15.25 → To $ 500.00 You charge: $ 12.50
