Welcome to the site! It's nice to have you here with us :)
At the top of everybody's list of tips, I'd say is READ/RESEARCH, READ/RESEARCH and READ/RESEARCH some more! Start off by reading through the various post on our forum, blog and education section. Also don't forget to download your copies of our bonus guides - you'll find them quite helpful :)
Then we suggest you decide what type of products you want to sell. Generally it's best to start selling something you are interested in because you are going to be spending a LOT of time thinking about it! Do you love fashion or movies? Perhaps you feel excited about the thought of new gadgets and technology? It's likely that there are plenty of other people who also share your interest - giving you an instant audience for your product. One idea is to jot down your interests and then make a list of products that are related to these interests (we recommend staying away from electronics to begin with as warranty issues can be complicated to manage).
Once you've thought of a couple of ideas, it's time to start researching suppliers. This is where SaleHoo comes in. Use the search box to look for the product(s) you want to sell. When you've found some suppliers who fit the bill, send them an email asking what the best possible price is that they can give you for the products you wish to buy. A small tip for you: if you buy 20+ units at a time, you should be able to negotiate a better deal. It's also a good idea to contact more than 1 supplier before you start buying to compare prices.
If you have any further questions/concerns please feel free to drop us an email at email@example.com or post it right here in our forum!
See you around - Cheers! :)
