Every courier company will have different requirements for the products to get delivered to the desired locations. Your products will be of a particular size and they may need special safety elements while shipping. Your delivery location may vary. All these elements will affect the overall pricing for the service and there is no way to guess it yourself. So, you should ask the company and confirm the pricing beforehand. You can feel free to look for another company if the pricing seems unacceptable.
Mode of delivery
You may know that there are three ways to transfer a product from one place to another. The courier company may be using all of them (air, sea, and road). Else, they would use certain ways alone. It is better to know the mode of delivery to have clarity of the process.
