The Custom Error Messages feature of the Advanced Shipping Manager gives you the ability to create your own unique error message for your E-Commerce Store. When a customer selects an invalid shipping method, they receive a generic error message. With this feature, you can now choose to compose your own message.
Don’t forget about one of the Advanced Shipping Manager’s original features, the Block Shipping Methods feature. It allows you to block specific shipping methods for specific items saving your customers confusion and saving you customer service calls.
