Buy products from suppliers at wholesale prices, sell them on Amazon for profit. Simple concept, but finding the right products takes work.
The Challenge
Suppliers send you price lists with hundreds — sometimes thousands — of products. Your job is to find the winners: products where you can buy low and sell high on Amazon, after all fees.
Checking each product manually takes forever. You need to find the Amazon listing, check the current price, calculate all the fees, look at sales rank, and see if there's actually profit left. That's why sellers use tools to do the heavy lifting.
Types of Tools
