Private Branded Product (Mainstream)
 

So I have a health supplement product that I want to privately brand and I found a good company to do business with. I actually use their products. They're great with orders, fast within 2 days, etc. They offer labeling for me.

Do you have any experiences with ordering and reselling products (not drop shipping)? Care to suggest any huge tips to minimize the amount of mistakes I need to learn from?

Its a supplement business with huge repeat orders so I doubt I won't have an issue becoming a brand people coming back to. The best part was I got a domain that is totally on point with my idea.

Anyway I would love to hear anything you've learned that could save me before I start.
