Yes, we do accept book bundles for distribution!
A bundle is when more than one book is added to an edition, generally about the same topic. For example, you have written four different books about online marketing that are already published separately. You can include all four of them together in a new edition and call it 'Online Marketing Bundle'.
In the case of book bundles, our store partners accept higher prices.
This format is typically used for ebooks and audiobooks, but it can also be applied to print-on-demand.
The name 'bundle' is usually reserved for nonfiction publications; for fiction, most authors opt for calling it a 'box set' or 'collection'. However, feel free to use any of them, it is totally up to you which one you find the best for your titles!
