Digital / Physical goods on in-app purchase
<p>I’m developing a Marketplace App of the courses for the Learning Purposes and we don’t have any kind of control over uploading of Physical content( CDs, DVDs, Hard Copy of the book, etc. ) or the Digital Content (Videos, Audios, Ebooks, etc.) on the courses uploaded by the seller for the consumers to purchase.</p>

<p>So could you please suggest what kind of payment method should we use apart from In-App purchases? </p>

<p>If we are bound to use In-App purchase then how should we implement it in our App and also we have following queries to clear our doubts for the monetization of the app.</p>

<ul>
<li><p>Could we add n number of courses dynamically having digital and physical content with In-App Purchases implemented? In our app the courses limit is not fixed, it can be 5000, 10000 or 100000.</p></li>
<li><p>Will it be possible for the sellers to provide any kind of discounts for the existing courses?</p></li>
<li><p>How could we manage(addition or deletion) the courses dynamically with In-App purchases?</p></li>
</ul>

<p>I researched on google but no solution was found. Some solutions were found on StackOverflow but we can't find  proper guidelines for our queries. Thanks :)</p>
