Through July 5, they are on sale for $2.00 each, DRM-free and in multiple formats, at Fictionwise. It looks like the best way to get to them is to follow the author links: Jacqueline Lichtenberg and Jean Lorrah.

Coupon code 070111 for 60% off everything. Via a post at ebooks, which has some other suggestions.

(Hmm. Geoff Ryman is GoH at Readercon this year, I've never read any of his stuff, and Fictionwise has The Child Garden for $4. What else might I find . . . ?)

(Answer: A whole bunch of Dave Duncan's books, though not as cheap, and many books from Small Beer Press, and now I have to stop looking and do work.)
