Many people resell products online, at flea markets and in catalogs for a profit. Some do it for extra income while others turn product reselling into a profitable full-time business. According to James Stephenson, author of 202 Things You Can Buy and Sell for Big Profits: "The Internet has not only made it easier to sell products into the global marketplace utilizing online sales venues such as eBay, e-commerce websites, e-classifieds, and e-storefronts, but to also source a nearly limitless number of in-demand products, which can be bought cheaply from domestic and overseas suppliers and resold for a handsome profit."
List your hobbies, activities and other interests. Note your areas of expertise. Then write down products or types of products that are associated with these activities. This will get you started selling products you are already familiar with. You don't want to start selling fishing equipment, for example, if you have no idea what a rod and reel are.
Find your products. Look for a wholesale distributor of a wide range of items or approach companies individually and ask how to purchase the products you're interested in wholesaling. There are a number of wholesale distributors online. A search for "drop-shipping products" or "wholesale products" on your preferred search engine will yield many results. A quick email or phone call to the company that creates the product you want to sell should yield a wholesale application.
Purchase your products or arrange to have them drop-shipped by the company. Drop-shipping is ideal, especially for a new product-reselling business, because all you have to do is market the product and collect the orders. The shipping and handling are all taken care of by the company that makes the product, saving you the investment of purchasing a lot of product up front. However, if you are reselling products at a retail location or flea market, you'll have to purchase your products ahead of time.
Create a website or a print catalog to offer your products. This can be your main source of sales or an addition to your flea market or online auction sales. Your website should be simple to use and offer your customers a concise description of your products and no more than one extra click to the ordering page.
Find flea markets, craft fairs and other outlets to sell yor products directly to your customers. If you are trying out a new line of products, renting a mall kiosk during the holidays (or during another appropriate season for your product) can help you find out, with minimal investment, which products will succeed.
Advertise and promote your products. Use social media, a blog, article marketing to promote your products for free online. Place ads in targeted, niche publications both print and online to generate interest in your products. For example, if you're offering organizational products for crafters, find popular crafting blogs and magazines and place ads in them. You could also offer to write a guest post on a crafting blog or offer your product for free to the blogger in exchange for a product review.
