Selling cot bedding door-to-door

Have you ever heard about the special way of selling a product or running a campaign called door-to-door? I think that you might be familiar with it because it is really profitable among people and most of the friends that I know told me that they know what it is. That is why I have made this assumption that it might be a similar case with you. Was I right about it? Anyway this method is very often used in political campaigns in countries where it is allowed. Representatives of a particular party walk from door to door and are trying to convince people that they should vote on their political party. It is a very effective method. I am not really sure whether it is good for advertising products. Recently I have been hired in a company where my task was to sell cot bedding by using the door-to-door method. It was really exhausting as you can imagine as I have been walking from house to house trying got convince people that this cot bedding is what they need. I think that the whole idea is wrong. Why? Because I don^t think that this is a product that a lot of people need and that is why there is no sense in going to every apartment or house to ask whether they want to buy it. Do you understand what I mean? After all cot bedding is not something that we need suddenly.
