Uncommon Project - Bookshop.org
BookShop.org allows customers to shop from independent bookstores. They take a much smaller cut than other online sellers (i.e. Amazon) and operate as a B Corp supporting public good. I mentioned the site in a recent blog post after hearing about the site on a Reset podcast, where the founder indicated books generally about the same as other online sellers.
Here's more about BookShop from the site:
Bookshop is an online bookstore with a mission to financially support local, independent bookstores. We believe that bookstores are essential to a healthy culture. They’re where authors can connect with readers, where we discover new writers, where children get hooked on the thrill of reading that can last a lifetime. They’re also anchors for our downtowns and communities. As more and more people buy their books online, we wanted to create an easy, convenient way for you to get your books and support bookstores at the same time.
