Delivery" button at the bottom of the main page of my shopping information or the "Apply for Bundled Delivery" button at the top right.

After checking all the products you want to ship in batches, click the "Apply for Bundled Delivery" button at the bottom and your request for bundled delivery will be delivered to the seller.

It is only available for the same seller's goods, and may not be reflected if the seller is already working on shipping.

However, depending on the characteristics and volume of the product, it may not be possible at all, and the buyer did not apply for bundled delivery, but bundled delivery is possible, so the seller can do it arbitrarily.
