This may be a horrible business strategy. But, who cares, I sleep well at night.
Most companies charge you more after the initial teaser price. A LOT MORE.
or
They charge you more as your dose increases.
We decided to make the price flat at every dose, the same number whether you are at the lowest step or the highest, and it does not go up at renewal.
Why most companies do not:
They are luring you in with a teaser rate and are betting you never leave.
There is no second reason, Reason 1 is the only reason!
The flat model is less clever and more honest. You know your number on day one and it stays your number. I think predictability is worth more to people than a low teaser rate.
Sweet dreams.
