Fbm in Vancouver Canada.

Hey everyone. I started selling on Amazon a couple of months ago. I bought a few products to sell, some used books.

I’m doing fbm just trying to learn and figure out the process but I sold a couple of things yesterday. They were listed $20 + 5.54 shipping.

And when I went to Canada post it costed me 25 to ship.

Same with book I sold. Sold the book for 10 but shipping costed me 25.

What did I do wrong ? If anyone has any advise.

It’s part of my learning curve I guess but I doubt that if I sell another book and post the price + 25 dollars for shipping. I doubt anyone would buy it

Has anyone encounter this before??
