where to buy to sell on amazon is a question new sellers often ask when entering the FBA model. Popular sourcing options include international platforms like Alibaba for private label goods, or local options like liquidation sales, thrift stores, or wholesale clubs like Costco and Sam’s Club. Many sellers begin with online arbitrage using tools that monitor price gaps between eCommerce platforms. Regardless of the method, it’s vital to validate demand, calculate profitability after fees, and ensure compliance with Amazon’s selling policies before listing products.
