@atpfm I would rather get asked for money every time I listen to the podcast than listen to advertisements every time I listen to it.

This is what most german podcasts do and it seems to work for them, moneywise not as well as ads but still prettty well.

Asking for money, or for them to buy a book or merhandise you did, is in my opinion much more respectfull to the audience than forcing them to listen to random ads therefor I'm sceptic about you saying that you don't want to sell some older merch again out of respect for the audience while you're sending at least three ads per episode and don't offer a payed add free version.
