If you choose to ship your order via Express shipping, you will receive 10% of the cost of shipping back in bonus points! Just like with normal points for an order, these points will become available one week after your order has been fulfilled in full (all items have shipped).
For example, if Express shipping for your order costs ¥8,000, you will receive 800 bonus points for your order. These bonus points can actually make shipping via Express cheaper than other options, like Regular.
Please note that bonus points for Express shipping are only available during checkout. Any shipping upgrades that occur after checkout will not be eligible to receive bonus points.
Additionally, bonus points are only available to orders placed after the launch of the feature. Unfortunately, orders placed before the launch cannot have points retroactively applied.
