I felt exactly like you with I started my training with SaleHoo support :) and I'm sure many other members can relate to how you feel right right now too!
Yes, the best starting point is to go through the education tab. Don't forget the bonus guides (pdf guides) in the guides section, Link hidden: Login to view I'm sure you'll find these quite helpful too. Especially our New User Manual - where we explain how to get off on the right footing with the suppliers you would like to work with and lay the groundwork for negotiating the best prices and creating long-term relationships.
Then once you read through everything in our guides section, do find time to go through our forum, you can easily search and browse for topics or products/suppliers you are interested in by using our 'Search in the forum' tab on the upper left side.
Our blogs are a good source of advice and info too!
Oppss..I didn't mean to make you brain hurt some more :) Just want to be sure you don't miss anything.
