Just by what you've said there, I don't think you have been doing enough reserach.
I'm in Aus, and im making a good profits.
I think firstly what you should do is to not assume electronics have the best profit, because they don't. That market is flooded with people usually selling at below wholesale price.
I am trying to get some people on board with my new wholesale program on my website (below in my sig), please check it out, and contact me if you have any questions.
Don't give up!!
