There is more to shipping costs than just actual postage or carrier fees. For example, there are handling costs such as packaging material, labor costs to pack and fulfill orders, and transportation costs. Furthermore, we also spend time at the post office or other carriers. Most importantly, we try our best to keep shipping costs as low as possible even in the face of rapidly rising costs. Even with the high cost, the convenience of having orders delivered to your door should make up for the cost.
