1. As mentioned above, it's marketing. In marketing as in many professions, very few intelligent professionals. For any company, every advertising campaign is a headache (except for image ads).
Usually a businessman (owner, General, ...) wants to be sure what the effect would be from the marketing. There are marketing Department, he eats a salary, must have something to offer, brings any nonsense with insane costs without any guarantees.
How to calculate the effect of lower prices?
After all, if you come to the same customers, it is loss of profit.
So we go to step 2...
2. New trend: "buy the buyer"
A perfectly clear principle. I only came for a specific buyer. And there is some assurance that it is unique and new.
If I spend my share of time in half a year, it is theoretically possible to agree to those who came last time could not buy, etc.
Why should I buy a buyer?
3. "Buy attention"
The attention of the man now so much dispersed, all fighting for him.
If I have good service, I'll give it to you to try for free.
You pay attention to me.
And if the service (product) is really worthwhile you will come to me again.
Ie is a service for those who really tries to be better. Who does not need to peddle. Who appreciates and respects the client. One says sale 80% and writes the old price multiplied by 2.
Unfortunately in our country such a minority, so such a cool idea, and strive to flush down the toilet in the Wake of the crowd (for quantity we sacrifice quality)
Well the most basic answer to the question.
This is especially beneficial to companies service.
Those who have a really small cost.
And time constraints (only in the morning ...) sebestoimosti can be equal to 0.
For example, a ski resort (the lift is still spinning, the snow is ..)
Spa (massage and so paid a salary, and they idle afternoon)
Movie (halls are usually empty)
