Reflowable vs Fixed; Epub 2.0 vs Epub 3.0; Kindle vs iBooks - factor in the combinations, and you could produce eight different versions of your ebook right there. In fact, I saw an article about people who go to insane lengths to release their ebook in half a dozen flavors, though I can't locate it right now.

My first book will probably be reflowable, though I'm not yet certain if I want to go with Epub 2.0 or 3.0 (or both). I'd like to sell it on Amazon and Apple both. My second book will probably include a fixed version, as it has far more images and tables.

So I was wondering how people who release multiple versions of various titles promote and advertise them.

I assume you don't need to specify "Amazon Kindle" or "Apple iBook," because people just assume that anything sold by Amazon will work on a Kindle. Ditto for iBook.

But do you tell prospective customers that your design is fixed or reflowable? Do you tell them that it's Epub 2.0 or Epub 3.0?

If so, how do you convey this information? Do you include the words "Epub 2.0, Reflowable" on the front cover (which doesn't seem practical, in most cases), or is there a better way of doing it?

On a similar note, do some people sometimes charge more for certain versions? For example, a simple reflowable book that sells for $25 might sell for $30 for a more ambitious fixed version that has bigger pictures or $50 for a deluxe version that includes some embedded audio or video files.

Have you seen people doing similar things?
