I just learnt about Bookshop! According to its website, it splits 10% of sales to the author, and 10% of sales to your favorite local independent bookstore. How cool is that?
I have not used it (having just learnt about it) so I would love to learn about it from people who have! What do you think of it?

For authors interested in Bookshop, they also have this PDF to read, and for bookstores they have this link.
