Hiss and a Roar
Tim Prebble does not only sell sound effect libraries, he also offers parts of them for free. The only thing he asks in return is that you subscribe to his newsletter.
PacDV
The free sound effects at PacDV seems to be very similar to those at SoundJay. You can download them directly without registering. The sound effects are either mp3 or wav.
Partners in Rhyme
The Partners In Rhyme site has been around since 1996. Their main focus is to sell royalty free music and sound effects but they also have a free section. The site is somewhat chaotic and quite tricky to navigate.
Sound Jay
The audio at Sound Jay seems to be similar to those at PacDV. Every free sound effect is available in both wav and mp3. No registration necessary.
The Recordist
Frank Bry’s site The Recordist has a collection of free quality sounds in mp3 format. Note that the sound effects are only free for personal use. If you want to use them in a project you’ll have to buy a license.
