Please comment before purchasing as I am also selling on other platforms. ★ Single purchases are not allowed. ★ For new releases only, if the set includes new releases and the new releases are priced at 750 yen or less, they are 500 yen each. So, two new releases would be 1000 yen + shipping. ★ For new releases in a set priced at 850 yen, please calculate them at 600 yen each. ★ If you are unsure about combining with used books, you can purchase first and select your choices up to 2 days before the shipping deadline. Please check the books available below. Due to people checking stock for fun, those with no transaction history or only a few transactions must purchase within 2 hours of my response. Others, please purchase within 6 hours. (If you comment late at night, I will create a dedicated listing in the early morning, so please purchase immediately after waking up.) ★ Prices are determined by occasionally searching for the book title and adding 150-200 yen to the listed price. Therefore, prices may go down or up. ★ The author's name in the title indicates a new release. ★ Important requests regarding transactions are written in my profile, so please read it carefully, agree to it, and write "[Profile read]" after purchasing, and then send a brief message. ★ For convenience store payments, please pay within 24 hours! ★ This price is for sets including used books, so if you only want new releases, please check the prices on the new release bundle page or the new release set sale page. ★ I get emotionally down when people decline after I've calculated the price (T-T) ★ Please check the price yourself before commenting, as some people decline after inquiring. After commenting, a dedicated page will be created – do not purchase immediately. ★ No returns or cancellations for any reason. ★ You can combine with used books from other new release sets. The price setting is based on new releases, so there is no price change even if you combine with older books from other new release sets. ★ No price reductions. You can choose one book from the 2-book-for-600-yen sale (excluding individual sales), but please "like" it so it's easy to find. For books with other prices, the difference can be added. Books released in 2023: +100 yen Books released in 2024: +200 yen
