Yeah I here your pain buddy, sometimes its a mission to find new niches out their and make a decent return, this is my philosophy for selling online, if the walmarts of this world sell it, dont bother. you can play around with stuff like liquidation.com and buy surplus products and give that a shot or stick to a niche that wont be found on your local stores, i think theirs a market for everything big or small. You can also try hand made items. example i live in florida local american indians make hand made mocasins (sandals) they look different, their hand made and have a catchy story. its a niche if you are going to have sell comodoty products like walmart doest then you better be able to compete with their pricing which is not feasable and a waste of your time and money.
