I've raised £500 to get anti-racist literature into the hands of those who want to educate themselves

Borrowing the idea from the amazing fundraising initiative by Dr Jess Wade which is helping to distribute free books that fight for racial justice: Superior by Angela Saini and Why I'm No Longer Talking to White People About Race by Reni Eddo-Lodge. I wanted to follow suit and help spread the word of a book that really helped to open my eyes and shape my thinking about race and class in the UK: Akala's 'Natives: Race and Class in the Ruins of Empire'.
This fundraising campaign will be used to buy copies of Akala's 'Natives' and to distribute them to people who want to educate themselves. All proceeds will be used to buy / ship books. The only condition is that you don't only read the books, but you share them, discuss them, and join the fight to make the world a more fair place.
Seeking some advice. Rather than buy the books from Amazon or a large bookstore, it would be great to buy from black owned bookstores. Can anyone help with recommendations?
