Research. You need to know what others are selling before you decide what wares you will offer. Lots of people sell handmade items, but those who work hard to make their items unique in some way are the ones who truly stand out. After you’ve decided on a product, check out the other sellers on Etsy and find what they’re offering, and then figure out how you can do it differently.
Some scams might involve asking you to pay for a “training” book or CD that explains how to make money in a certain business. Others charge for supposedly “exclusive” products that you’re supposed to sell at a premium. Avoid both of these scenarios. Remember, you should never have to pay to get a job. And if someone asks you to, you can be sure that it’s a scam.
