Until the end of the year, SFWA and HWA members can get 20% off any
order in the Apex Book Store. HWA members only need to enter HWA20 on
checkout. Likewise, SFWA members should enter SFWA20 on checkout.
If you've been thinking of picking up The Apex Book of World SF or The
Changed, now would be a great time!
