[Renewal Commemoration / 29% UP on Purchase Price] Sell Books and Manga Without Leaving Home. "Book Supply," a Mail-Order Purchase Service Used by 1 Million People, Fully Renovates Website

Book Supply Co., Ltd. (Head Office: Suita City, Osaka Prefecture, Representative Director: Shingo Yabuta) has fully renovated its mail-order purchase website (https://www.booksupply.jp) on July 7, 2026 (Tuesday). This comprehensive renovation of our mail-order purchase service, which has been used by over 1 million people cumulatively since its founding in 2000, aims to create a website that even first-time users can navigate without confusion. To commemorate the renewal, we are also holding a limited-time campaign offering a 29% increase on purchase prices from July 7, 2026 (Tuesday) to August 11, 2026 (Tuesday).

Key Points of the Mail-Order Purchase Website Renewal

This renewal, themed "Towards a website that even first-time users can navigate without confusion," includes the addition of a new "Page Exclusively for First-Time Users" and significant enhancements to genre-specific pages for items such as books, manga, CDs, DVDs, and game software.

"How does mail-order purchase work?"

"Can I sell this before sending it?"

"How much can I sell it for?"

We aimed to create a site that can answer these questions, which first-time users are likely to have, without them having to browse multiple pages.

We will continue to make improvements to provide a more convenient website for our customers.

New dedicated pages have been created for each genre, including books, manga, CDs, DVDs, and game software. Information that users want to know for each genre, such as reference purchase prices and tips for selling, can be found on a single page.

Contents of Each Dedicated Page

Reference Purchase Prices by Genre ・Major Categories (e.g., Novels / Business Books, etc.) ・Sub-categories (e.g., Literary Works / Mystery/Suspense, etc.) You can check the reference purchase prices for each of the above. This was redesigned in response to requests to "know the estimated selling price before sending."

Books Dedicated Page Top Major Categories (Novels / Business Books, etc.) Sub-categories (Literary Works / Mystery/Suspense, etc.)

*The reference purchase prices listed are estimates and may differ from the actual purchase price depending on the condition of the item and market trends.

Tips for Selling High by Genre Even for the same product, a little tip can make a difference in the purchase price. For each genre, we have summarized "Points that make items sell for more" with illustrations.

For example, for books: "Sell new releases quickly while they are still popular," "Check for fading, sun damage, or dirt before sending," "Don't forget to include any accessories that came with the book."

We also provide tips tailored to CDs, DVDs, and game software for each genre.

Check "Can This Item Be Purchased?" with Photos We have made the criteria for purchase, which were previously explained in text, available with actual product photos. Items are categorized into three groups: "Can be purchased," "Condition with reduced price," and "Cannot be purchased," with actual product photos displayed side-by-side.

You can determine which category your item falls into by looking at photos, not just text.

Renewal Commemoration! 29% UP on Purchase Price Campaign

A special campaign lasting about one month to commemorate the renewal of Book Supply's mail-order purchase website. We will add 29% to the purchase price.

For example, if you normally receive 5,000 yen for a box of books or manga, you will receive 6,450 yen during the campaign period. If it's 10,000 yen, it will be 12,900 yen, and if it's 20,000 yen, it will be 25,800 yen. The more you send, the greater the additional amount.

A 29% increase from Book Supply is a rare special offer. We don't know when you'll be able to receive this offer again. The period is only about one month, from July 7th to August 11th.

Why not take this opportunity to sell the books, manga, CDs, DVDs, and game software gathering dust in your home?
