We partnered with bookshop.org because we want to support independent booksellers whenever possible. However, we have also included Amazon links because some of the books are only available on Amazon. Plus—because they are a union-busting, tax-dodging, monopolistic mega-corporation—most stuff is cheaper on Amazon. We all have a budget and some days yours might not include fighting the tide of late capitalism without the support of any regulatory agencies. We get that.
