How much do you have to pay to ship a Box?

Excuse me, could you please clarify for me the cost associated with shipping a box? I'm curious to know what kind of fees I might be looking at and if there are any additional charges that I should be aware of. Is the price fixed or does it vary based on factors such as the size, weight, or destination of the box? I'd appreciate any information you can provide to help me better understand the shipping costs for a box.
