Advertising is bridge between a seller and buyer. What is your opinion in this regard?

I disagree with that statement: you can sell without advertising, and you can advertise without selling.

If you advertise for a cause, there is no buyer or seller.

There is this brand of broasted chicken in Jeddah, Al Baik, who is very famous in KSA and they never advertise.
