Welcome! It's great to have you here!
Since you are still new to all of this, the best advice I can give you is RESEARCH, RESEARCH, RESEARCH. That's where newbies always go wrong. Because of excitement and the drive to start sourcing, selling, and earning, you easily fall for the traps of scammers that offer you products at unbelievably low prices. I'm not an exception to this when I started out. So the best way to avoid this is by researching. If you find a supplier that interests you and you are unsure, do a Google Search on them or enquire about them here in the forum. There are other tips that you can find by clicking on the 'Education' Tab found on the top-right of any SaleHoo Page.
There is a wealth of information here in the forum so have a look around. Also, don't forget to download the SaleHoo Bonus Guides by clicking on the link Bonus Guides *New* on the left-hand side of the page.
If you have any questions at all, please don't hesitate to post it here or contact us at firstname.lastname@example.org
I wish you all the best and I look forward to hearing more from you.
