Rakuten features a lot of stores, and sometimes, you can buy the same item from multiple stores. In most cases, it doesn't matter which one you choose, as all stores are trustworthy, so feel free to go forward with the store of your choosing.
If you are planning to buy multiple items, you may want to order all of them from one store to save on the domestic shipping fee. Click "View the seller's other items" to see more items from the store. Items must be purchased at the same time in a single order.
