Fudjj is right! You can also try selling a few stuff from around your home. Nothing beats knowledge gained from experience and selling stuff from around the home is the best way to get it without any risk.
After some practice with goods from around the home, we recommend buying small wholesale lots of products that most people use on a daily basis. Many of these products are excellent sellers, plus they are fairly easy to get hold of. A lot of new sellers make the mistake of trying to be all things to all people.
Just keep it simple and small to begin with..Cheers :)
