Hey @Lizzy, I think what the instructor was referring to is Udemy's move towards differentiated sales pricing. We’ve been experimenting with differentiated sales pricing to improve how we market courses during promotions. Differentiated sales pricing takes into account different variables, including topic, student response, number of competing courses, and assigns an appropriate discounted price during a particular promotion. Since no two courses are alike, we firmly believe that they shouldn’t be priced alike either.
If this instructor is opted into Udemy's Deals, then we have been setting their sales prices already. Nothing has changed there. However, the way in which we are setting sales prices has been gradually shifting. This doesn't mean that courses will never be on sale for $9.99. It means that we're moving away from a world in which all courses are on sale for the same, low price. There's more info about this in the blogpost I linked in the first paragraph.
