Everybody knows that a businessman needs business cards to conduct business. If you try to compare various ways to promote a business, you will discover that business cards are indeed one of the cheapest ways to promote a business. The question is how to distribute business cards. Probably one of the most obvious situations is after closing a deal or when you just made a sale. What is the right amount of business cards to hand out? It is at least seven or eight. One business card is not usually enough to make a difference. You need to give a person more than one so that the person will have enough of them to give to other people if an opportunity arises.
