When you're searching for products to sell online or in stores, do you stumble upon items that are sold out/unavailable on Amazon? Even if the product has a dismal Amazon Bestseller Rank, it typically sells very quickly and at a great profit. Here is a tool (http://soldoutproducts.com) I use to find out of stock products on amazon to sell. Post a comment if you've had success selling 'Sold Out' items too.
