I've added Elizabeth Ann Scarborough's four titles at Fictionwise to my list too.
For SF fans, I do recommend Brian Stableford.
I read his "The Dragon Man" last year, and liked it a lot. I have his SF/Fantasy on my list.
R A MacAvoy was already on my list.
The Lois McMaster Bujolds that aren't available through webscription.net (where they're mostly available as omnibus volumes for $6, which probably works out cheaper). As a fantasy, I highly rate her "The Spirit Ring".
I've added the longer Marion Zimmer Bradleys that I didn't have, also several of Piers Anthony's SF/Fantasy.
Some Mercedes Lackey - although watch out, some of the title there are still overpriced, even at 60% off.
I've also added in the available editions of LightSpeed Science Fiction magazine ($1.02 each!)
With everything else, I now have a list of 100 books for $217.79. And some more on my wish list to be bought with my micropay rebate.
But since that's about a year's worth of reading matter, I shall give it a little thought overnight. It does seem to be an amazing bargain.
