[Sell Without Getting Wet] Sell Books from Home on Rainy Days. Book Supply's 'Rainy Season Purchase Debut Campaign' in June / 26% Increase in Purchase Price

Book Supply Inc. (Headquarters: Suita City, Osaka; Representative Director: Shingo Yabuta) will hold a limited-time campaign from June 1st (Mon) to June 30th (Tue), 2026, where the purchase price will increase by 26% for those using the mail-in purchase service for the first time. Eligible items include books, manga, CDs, DVDs, and game software. Simply enter the campaign code [H26METES] when applying, and 26% will be added to the regular purchase price. The rainy season, with its increasing number of rainy days, is a time to spend slowly at home. It is the perfect timing to start organizing your accumulated bookshelves. Many people think, 'I want to sell the books and manga piled up at home,' but often put it off. This campaign is implemented as an opportunity to let go of things you've been 'curious about but haven't acted on' in your spare time. With Book Supply's mail-in purchase, all you have to do is 'pack them in a box and hand them over.' Professional staff with 25 years of experience in mail-in purchases will carefully appraise each item. After appraisal, the transfer process is completed in as little as 2 business days.
