Overlap between readers of freebies and readers who buy

[Karen]

I've been working on a free story set in the same afterlife as Wander Home. I'm also planning to make my previous novel, Twin-Bred, free wherever I can once the sequel comes out this spring, in a new edition including the beginning of the sequel's first chapter. The idea was to lure readers from the freebies to the still-cheap-as-dirt :-) ebooks. I'm wondering, though: do more than a tiny percentage of those who download free books spend any money, ever, to buy books? Thoughts, experiences?

If the subject is what I'm interested in, I've paid as much as about $7.00 for e-books. I haven't purchased any print books lately because if I did, I'd have to own a castle just to hold my books. I've got over 1,000 e-books at the moment and at least 1/4 or more were purchases.
