In layman's terms, price refers to the actual price of the product. Price point relates to a theoretical spot that the price could be raised or lowered to for a particular strategy.
Price point = theoretical. The app has an established price. This is my point. If a company is trying to establish an initial price based on consumer feedback, sure, use it to identify different options. But not on a price that is actually set in stone. My point is, people grossly misuse/overuse the term to sound clever.
And quoting Urban Dictionary was not an attempt for me to say the word doesn't exist at all.
