This is generally a contest on which your luck is run. The winning contestants are awarded prizes. Only those people win who have entered their names in the contest and then when their name is drawn out of many other names they become the winners. These contests usually have limited eligibility by national, local, or other geographical factors. If you want to promote your product then this is one of the most popular ways of marketing techniques. And for sure by applying this technique your business will become very popular. In these contests we make sure that customers never have to pay to enter or that would be conflicting the lottery laws. Now there are even online sweepstakes which people can enter easily from the comforts of their home. Some big prizes that people win are like cars, cash, houses etc. And some small prizes are like iPods, Mp3 players, etc. There is no cost of entering these contests and neither on receiving the prizes.
