I was thinking about success with Amazon’s FBA (Fulfilled By Amazon). It boils down to the 3 topics in this blog Title.
Find It! Find Profitable items to sell.
List It! Get it “on the shelf”.
Ship It! Get it to Amazon’s warehouses.
Repeat! Do it again — and again — and again — and… again!
Along the way, there are numerous more things to do, but if you aren’t doing these three things, you aren’t going to be successful.
