And take that.

Science Fiction and Fantasy Writers of America (SFWA) removes Amazon buttons after Amazon's removal of Macmillan's buy buttons. Their goal is not retaliation, but to keep members' books available for purchase. If Amazon refuses to sell them, then links must, of course, go somewhere else -- indiebound.org, Powell’s, Barnes and Noble, and Borders, which I thought was owned by Amazon, but apparently still has its own online storefront and identity.
