Woocommerce is one of the most popular online shopping platforms available and for good reason. Woocommerce is built under the Wordpress system, which is the #1 choice for bloggers. Though Woocommerce is free, you might need to download plugins and themes to create a professionally looking online store. The other option is Shopify (not free), which is super user friendly and you don’t need any hosting provider to start. I suggest you try them both and see which works best for you situation.
