It is of course an observation that holds almost always, like Zipf. But only for very large numbers. However, this bit > But the remaining 20% (200)will buy that $40 package instead of $10.

If you take it away from your $10 tier, you may lose clients there. It's a balance, and for a starting business, a precarious one.
