If you manufacture boats of various types, then the only you to make a båtar available for purchase to common people is through proper advertisements. But if you are new seller, then, it may not be possible for you to bear the expenses of an advertisement.
Thus, the thing that is available for you are annons, because they are free and thus you can reach a moderate number of boat sälj within a very short period. The classifieds will appear in newspapers, so that they can reach the people.
Once you get enough revenue to place an advertisement on media, you can start doing it, once you cross the threshold.
