To add Shopify store as a WordPress Developer to a blog you can have three options. You can do a basic monthly price of $29.00 a month for a blog post, and add Shoptify. You can do a monthly plan of $79.00 a month for a blog post, and add Shoptify. Or you can go all out, and have everything for $299.00 a month, for a blog post, and add Shoptify. It really does not make a difference if you are a developer of WordPress, you just want to write a blog post, and add Shoptify yourself so that makes you have three options listed above.
