Existing of this kind of advertising its the answer itself. This is exist, because this is works. If noone want to buy a package, the marketing-analysts can see the numbers (zero order), and make the decision, to skip this advertising.

But we see it all the times. So the number its not zero. So there are enough people, enough customer, so the good decision its the continuing the ad.

So yes. Are there people who can still be fooled :) Many people actually.

Btw. i learn english since years, and as you can see, still pretty bad :D
