Ordering scientific books from abroad to Canada can incur various costs, including handling and duty fees. Many users recommend Chapters/Indigo for their lack of shipping fees and a wide selection of books. For example, one user shared their experience ordering a quantum field theory book from Amazon.com, detailing a total cost of $87.73, which included an import fees deposit but no sales tax or import duty. Alternatives like Book Depository are suggested for potentially lower prices, as they include international shipping in their costs. Some users are exploring used book options from different international sellers, finding prices that are significantly lower than new copies. Concerns about additional costs, such as taxes and import duties, are common, with users seeking clarity on whether these fees would exceed the savings from purchasing used books. The conversation highlights the importance of comparing total costs, including potential fees, when ordering books from abroad.
