All AF pamphlets are free to read/download.
To order printed copies of AF publications online you can do so from either Active distribution (London) or AK Press (who are based in Edinburgh for UK & European sales). A search on Anarchist Federation will reveal most of the AF items available, or type in words from the title.
For subscriptions to Resistance or Organise! (or both), and to order other selected pamphlets by post, visit: http://www.af-north.org
Both distributors above supply fiction and non-fiction books, zines & comics, poetry & artwork, music, videos, t-shirts, stickers, postcards, posters, diaries and clothing. Active distribution supply Zapatista coffee. AK Press are also a well known publisher of excellent anarchist books. You can also visit Freedom bookshop or other radical bookstores around the country to buy copies of AF publications in person (many of these have online stores for other material).
You can support these and other radical book publishers and distributors by buying your books from them rather than Amazon.
