For a bit of advertisment and publicity, anything could happen. Just become popular, and for some amoutn of publicity from you, you will be given anything for free or big chunks of money. Or if you know a good number of people, any business would want you to spread the word about them to these businesses. Well, the best way to spread these words around is by means of greeting cards. If its a new year, naturally you send out greeting cards to people you know, and if you get these cards for free, the sponsors would put their names at the bottom of the back page of the envelope, and they get the advertisment, and you get the free cards, and everyone is happy.

Lets say that someone wants to promote soaps and shampoo. They print their product at the back of the greeting card, and they give it to you for you to distribute, and when you distribute it to about 200 people, 200 people come to know about the new product, and you save about $200 in greeting cards expense. This way when you are given 200 greeting cards for free, or more, you would feel free to distribute it to as many people as you know, and the company would even distribute it for you so that you dont have to take the touble of stamping and sealing the covers and posting them.
