WooCommerce is a full-featured eCommerce platform gift wrapped in WordPress's ease-of-use and familiarity.
If you're running a blog already, you can now add a store alongside your content and start selling products to make a living from your writing. If you don't have a blog, you can build a whole new business selling something you love.
The WooCommerce core software is only half the story. The hundreds of themes available make it easy to create a store with a truly professional look. Add in a few of the hundreds of extensions and you can offer your customers services previously only available from eCommerce juggernauts, like Amazon, or better yet, features that aren't even available there yet!
I love WooCommerce. It's changed my life and it can change yours too.
