The issue isn't the import duty and VAT, the issue is the 20€ or more fee that the shipping companies charge for the privilege of handling the customs administration for you.
In Belgium for example books have 0% import duty and 6% VAT. Adding 20€, long delays, and a terrible customer experience (good luck trying to correct any data submitted to customs) to that is rarely worth the hassle.
