Yes, the shipping costs are borne by the seller. The cost of FBM self-delivery is higher because less than one kilogram is calculated as one kilogram. The loss is greater if the goods are light and large. In general, FBM self-delivery basically loses money. The more you sell, the more you lose.

In some cases, the return shipping costs must be borne by the seller. For example, if the delivered goods are wrong or are damaged when they reach the buyer, the seller cannot deduct the original shipping costs or return shipping costs from the refund. The seller must provide a full refund to the buyer.
