The sum is all that matters. The rest is just a weird number game.
As you say, your store preference depends on various factors. If C’s shipping costs are structured one way, you’ll prefer them. Another way, you won’t. You have to know all those details before you can choose. That’s my point: ultimately, functionally, there is no difference between a random store that won’t show you prices until you give them your location, and a ransom store that shows prices immediately but won’t give you shipping costs until you give them your location.
For example, if C sells something else that I want that's also much cheaper than a the other shops, and it won't increase shipping costs much, then that's the better option. If not, I may continue to shop around until I find a shop that combines low item price with reasonable shipping cost.
