If you're unfamiliar with the concept of arbitrage, here's how it works. Wikipedia describes an arbitrage as effectively, "the practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices." Clothier was able to identify arbitrage opportunities in the grocery industry with precision.
How to Get It: Customer service is the biggest work-at-home field, with companies including Spiegel, Hilton, Best Western, HSN, 1-800-FLOWERS and many others using at-home reps. Fill out an application with staffing companies such as Arise, Alpine Access, VIPdesk, LiveOps, and Convergys, all of which vet the companies who are hiring through them. If you need benefits, search through a staffing company that will hire you as an employee (Alpine Access, VIPdesk and Convergys do this) rather than an independent contractor. If you're a contractor, you may be asked to pay a small fee (between $15 and $35) for a background check. While a fee can be a sign of a scam, independent contractors are responsible for their own expenses.
