Aside from a particular series, I only order paperback books from Fakku.
I even use a bookmark to only show products that use the "Book" tag.
However, the title "Reconstruction!? Interspecies Insemination" uses the "Book" tag, but does not include a paperback when it's added to the cart.
When I reached out to support this was their reply:
"
Thanks for finding this and reaching out. We always appreciate the feedback, especially when our users catch things like this and bring them up to us. I'm sending this up for review to our team as well. We don't offer a physical edition of this title, but you may be able to find one by contacting the publisher - Full Moon. Let me know if I can help you with anything else.
"
Be advised that, so far, this product is still using the "Book" tag.
