That's all well and good, but it's not like I can make money giving away free copies, right? In my accounting, free copies are not tracked and don't count.
But sold copies count. How has giving away so many copies of Trang affected sales of Trust?
Well, they've had quite the impact! We're still not talking huge numbers here, but in January alone I sold 85% as many copies of Trust as I had in the last six months of 2012 (Trust came out in June). And that percentage is probably a hair smaller than it should be, since presumably some of December's sales happened after the late-December giveaways.
But of course I lost revenue on sales of Trang, right? Actually, it's been a good month for Trang sales--not as good as Trust sales, but good. (Let's hear it for the also-bots!)
Of course, if I make Trang permanently free, then I'll completely lose any chance to make revenue off that book, and as it sells more, that becomes a tougher call. On the other hand, all this is happening because Trang had free days! So I'm still confident that free is the way to go.
