This is why I have listed down the aforementioned websites on the basis of ease of use and popularity. However, in my personal opinion, the audio section of the Internet Archive makes it the best free music download website because I can find almost every artist there. You are free to choose the one which suits you the best, so go ahead and explore these sites.

So let's recap. If you want to open an online store but don’t have the skills or the time to build it yourself, you can set up a WordPress site and then install WooCommerce on top of it. But what about the design? Well, that’s where our WooCommerce themes come into play!

Contemporary electronic commerce can be classified into two categories. The first category is business based on types of goods sold (involves everything from ordering "digital" content for immediate online consumption, to ordering conventional goods and services, to "meta" services to facilitate other types of electronic commerce). The second category is based on the nature of the participant (B2B, B2C, C2B and C2C);[39]
You can use an off-the-shelf eCommerce solution like Shopify, which makes building an online store a quick and easy process. However, it will also mean less customization, as you will need to choose from an existing pool of themes and tools provided by the platform. If you opt to run a dropshipping business, eCommerce solutions like Oberlo will allow you to get the store off the ground and start selling in as little as few hours.
The Nexternal eCommerce Platform is a PCI Service Level 1 hosted system that enables brands to sell products directly to consumers or other businesses online, in person, or over the phone. The platform has been continuously evolving since 1999 and has features that will not be found in simpler applications. The software is a single database solution that provides a holistic overview of customer activity regardless of the channel the purchaser is utilizing. All orders can be managed in a web base Order Management System that is integrated with the major shipping carriers, allowing for efficient order processing. Our newest application, TrueCommerce Engage is a mobile point of sale solution that, uses the same database as the online catalog. 

Imagine an ecommerce platform that allows customer service reps to have a single view of a customer across all channels, a centralized order and inventory management system that can efficiently fulfill orders from all your sales channels, including brick and mortar stores, or utilize a customer's order history data to provide personalized and relevant offers. The possibilities brought to light with the advent of a complete ecommerce platform for business optimization and improved efficiencies as well as deepened customer engagement and satisfaction are limited only by one's creativity.
BigCommerce is most easily compared to Shopify. Both platforms offer a similar experience when building an ecommerce platform. Like Shopify, BigCommerce offers a range of prices and packages tailored to different types of businesses. The platform is highly customizable if you are comfortable with some light coding. It is also possible to use themes and templates to build your website, but some of these will come at an additional cost.
