Should you choose retail arbitrage or wholesale? Or maybe go big from the start and try private label? If you listen to most of the Amazon gurus out there, they'll make you believe that you have to choose one sourcing method - and the one they teach is the ONLY option that makes sense. I've found the opposite to be true - the various sourcing methods work best at different stages of your business, and the best path for you can only be determined by --- YOU.
