So here are common reasons why people fail making money on eBay!
Selling high risk items
Of-course you can expect the most profit form high risk items, however chances are you'll only be able to sell a couple of them before run into a trouble with the eBay policy. Selling just a couple of high risk items and for what, just to get your account banned isn't a business model, and it won't help you make you any consistent income neither. So stop trying to sell that Rolex, Hermes bag, or whatever it is that you're trying to sell for like $2-5 thousand dollars!.
It is very unlikely to "get rich overnight", however it is entirely possible to "get rich" if you know what to do! One of common mistakes new eBay sellers make is to list about a million items up in hope of making money fast but instead they get banned! After receiving such a blow that is highly de-motivational they decide that it's impossible to make money on eBay. So the trick is to go slow but steady!
Not enough items to sell
The rule of e-commerce states that you need to have a product to sell in order to make money doesn't mater online or not! Don't be afraid that you don't know what to sell on eBay. Go to eBay and do a quick search there on “eBay hot items”. Find-out what are the best selling items on eBay. Then go to Google and research on that item or product like "wholesale" + item name, more than likely you'll be able to come up with some items. Even if the item is from China, you should be able to sell it pretty quickly and get pretty good good returns if the quality is on par, in fact - about 80% of eBay is flooded with Chinese items.
At the end making money on eBay isn't that hard, in fact – it is one of the easiest ways to make money online. But the trick is that you need to know how to do it, the right way.
Happy Money Making on eBay!
