Hi and welcome, pattyco!
Selling something you are interested in can be a good start. We suggest using these three questions to come up with some ideas for niche markets to target -
1. What are your hobbies? (Fishing, hunting, scrapbooking, cooking, photography, languages)
2. What do people tell you you’re good at?
3. What would you like to be able to buy online but have trouble finding?
Magazines, newspapers and blogs are also very useful for brainstorming and researching new markets. It's also a good idea to keep tabs on what is happening in the news if you want to pick up on new trends. The trick is to analyze what you hear and read for product opportunities. For example, is global warming causing water restrictions in your area? Good products to sell might include garden hose timers, low-pressure shower heads, water purifiers and so on. And don’t forget everyday items - boring old every day stuff like bed sheets, socks, mugs, dehumidifiers, storage containers, etc - products that most people use on a daily basis. Many of these are excellent sellers, plus they are fairly easy to get hold of and they make up a huge percentage of all online sales.
A quick browse in the forum for products to sell may bring up a few ideas. You'll also find our blog very useful for getting tips on good products to sell.
When you're ready to start researching suppliers, just let us know and we'll be happy to help you out.
All the best!
