Let me explain. I just got my books, yeah! Thank you! The original shipping was 20$US (about 27.75$CAD) .. but then at the delivery, UPS adds a "brokerage fee" of 43.80$CAD (31.56$US). This is allegedly to process the import tax of 16.79$CAD which is added on top (but should have been 6.94$, since they are books), plus the tax on the brokerage fee... Using USPS would mean that the shipping is handled by Canada Post on this side of the border, not charging any brokerage fees .. and would probably charge me the correct tax amount. I know that using these shipping companies is often a question of ease on the shipper's end .. but if further projects could offer a USPS shipping option, that would be great for Canadian backers.
