Titles listed on our website are not necessarily in stock at our physical storefront. If a book says "usually ships in 1-5 days," that means it should be available at our distributor's warehouses, but it does not indicate whether we have the book in stock at the shop. We have some lists on our home page of books that are usually on the shelves, but those are manually updated by us. It is not currently possible for us to manually update every title on the site with its in-store availability. The fastest way to check on a title or two is to give us a call at 617-734-7323. If you have a longer list, or if you have a little more time to wait for a response, send us an email or place an online order. Thank you for understanding!
