Are the individual ebooks long enough to be an audiobook? If so, I'd do it that way. There are lots of ppl who want my novellas on audiobook. If they aren't linked in the listing, they don't realize the audiobooks are there. I'm curious to hear what other ppl think. The paper copies cost a LOT more to have them all individually printed. I've thought about printing one of my series as a big fat book, but then it won't come up with the listing. In in the same boat as you and havent decided what to do yet.
