Until you where you're shipping, the cost is not knowable.
You can build a feature for that but it adds complexity both in development, and (more importantly) the user experience.

Helpful sites handle this by offering to compute shipping at any point in the order, using my supplied postal code. Rockauto is one.
Less helpful sites make me finalize the order as far as possible. I've seen sites withhold shipping amounts until I submit my payment info.
Crap like this is what drives me back to Amazon and Ebay.
I said submit - as in to the site.
This is more complicated than you suggest. It's done to create consent for marketing emails. You can't see shipping costs without signing up for marketing email.
Exactly. Some sites have an input field on the product page, under the product price, so you can add your postal code and see the total price
Ordering somewhere else has a higher enough threshold that I avoid it.
