Hope all is good.
Questions about Audio Book uploads. Are there sites (and if so could you please list them) where if you upload the audio file for sale you can also include a PDF or Word File in conjunction?
I ask for two reasons. One from the consumer point of view if they are listening in the car and something stands out they can access that at home with the written words.
From a marketer point of view it would enable the ability to put an affiliate link or something to their website/blog/YouTube Channel, etc.
Thanks for the insight and all be well and safe,
