Takes a lot of time and patience ..Although dropshippers are on the decline as it isn't profitable anymore
Although there is no point in just selling the first thing you find.. You need to choose what you have a interest in otherwise it won't last ,I know lol ...But what ever you do don't pay for a dropship service as most of them a complete rip off ,again I know I've been doing it since 2009.
If you are really wanting to dropship the absolute best way is to find something unique is to go to all your local mini industrial estates and find them that way and try and arrange a service that both of you can agree on or ask them via email and arrange something that way ... I've got 3 suppliers I did that with
