Help?

In the payment page there is an option for selecting coupons. It comes after you click "proceed to checkout". It's in the same page where you enter your payment details. There you will see the coupon section. Next to it there is an edit button. when you click that it will show you the coupons you have, so choose the free 300 yen option. that's it! Thanks for buying it <3

Thank you!! I hope I can use my credit card hahaha

Wait can you guys please let me know how to support the author legally, and I don't really care if the language is in Japanese, English would always be better, but when it comes to supporting i don't care! I am planning to buy it so please let me! Thank-you!!
