You can organize your store by creating your product categories, sorting by any characteristic you choose. Your title, description, and the image will be included on each product page. In this way, customers can immediately evaluate all of your products. You can offer different pricing options for all of your products, including "pay what you want," in which the price is entirely up to the customer. This option allows you to give customers control over the cost of individual items (without a minimum price) or to set pricing minimums—a good option if you're in a competitive market or when you have higher-end products. You can also offer set prices per product as well as free products to help build your store's popularity.
