In the present world, most of the businesses are being done through the help of the internet. The best way to make some serious money is through online otherwise I think that you are losing some money. Many people are making millions of dollars just by selling the best products online. You can easily find best products to sell online. All you have to do is create a perfect matching website to your products. Your website needs to be professional as well as user friendly.
Remember if you wish to search many products in the same website you need to have a self search engine for your website otherwise it will be hard for your clients to browse through your products.
You can use any payment processor for selling best products online; I suggest 2checkout.com due to their support. You can also go through paypal.com but you can't expect support from them, it will be like you are on your own and also their charge will be too high.
You need a merchant account to start selling the products online and it will help you to accept payments of all type. If you have your very own product to sell online, you can do so by getting affiliates for your products or you can sell them in some online stores like ebay.com or amazon.com. You can also use your existing clients for future sales. I suggest you need to have your own online store in order to attract more clients and to make more sales. The buyers must be able to find you when they need to buy your product, hence having a short domain name will be better.
If you wish to be an affiliate, finding the best product to sell online is not a big deal. You can use many companies to search for a best product. Always visit their sales page and website before deciding to sell their products. Their website and sales page needs to be very attractive to reduce your work to sell the products and you also need to give some free products to your clients to make them buy the products through your affiliate links. You can use MRR products or PLR products to give free products to your clients.
