Stable income: Somewhat stable

Retail arbitrage involves buying products at a lower price from one place and selling them at a higher price in another. Setting up for retail arbitrage can be low, with costs ranging from $100 to $500 for initial inventory. Time to profit can vary but typically takes around 2 weeks to start seeing returns. From my experience and online sources, retail arbitrage can provide a moderately stable income. While some months may be more profitable than others, many people have been able to consistently earn from it. However, it's not as predictable as a traditional job, so there is some level of risk involved. I'd rate it a 2 out of 3 because although there is a decent baseline for income, it can be unreliable at times.
