We are planning to offer our customer the option between two different formats of audiobooks. The current one : AAC, and a new one MP3. The customer can chose between the two, the price is the sam, but the downloaded product change in accordance with his choice.



I know you developped "option" in e-junkie but I understand it is more for tangible products.



What you you suggest if we want to do so ? Would we have do duplicate all the database in order to create a new product per new format...or is there another option ?
