Earn your living online: 10 ways to increase your cash flow by becoming an eBay PowerSeller

More than 430,000 people earn part or all of their living selling products on eBay, but only 90,000 have achieved PowerSeller status by selling at least $1,000 worth of goods each month and maintaining at least a 98% positive feedback rating. PowerSellers have mastered the art of selling online through hard work and savvy buying and selling.

1. Focus on one product category.
Former co-workers Raymond Ramsey and Charles Ross Jr., co-owners of Cash Money Buyers in Chicago, opened a retail store in 2004 to buy and resell a range of products. On eBay, however, they specialize mainly in consumer electronics and power tools. eBay sales now account for 45% of Cash Money Buyers' business.

2. Buy low, sell high.

PowerSellers research prices and routinely monitor demand using free reports at the site. Ramsey and Ross buy their inventory wholesale, then clean, test, and prep the items before listing them. But "the beauty of eBay is that you may get a bidding war," says Ross. "Even if a saw is worth $100, [a buyer] may pay $200."

3. List in volume.

Cash Money Buyers lists about 200 or more items a month, while James and Brenda Daniel; owners of Best Designer Wear in Woodstock, Georgia, list more than 400. They sell new and used women's fashions from Jones New York Ann Taylor, and Gap at more than 50% off retail.
