pepperlandgirl4 is offering fic, as well as an original e-book. She's offering Star Trek as well as Angel, though she's familiar in a *lot* of fandoms.
katekat1010 is offering 5 pieces of fanart (1 for each of the top 5 bids). If you're not familiar with her amazing work, well, why not?!? Kate's astoundingly talented, and works across a wide spectrum of BtVS/AtS characters and pairings, as well as other fandoms.
I'm not a rabid Star Trek fan, but when I saw wook77's offering cross stitching of these absolutely adorable patterns for the characters, I knew I had to get one for Pepper. wook77 is actually offering 5 of these, each with a separate link: one, two, three, four, and five.
There are a ton of things being offered, and the offering threads are more than a tad daunting, but the mods have graciously created masterlists to help people navigate. Just check out the links on the right sidebar.
