You can upgrade to our Awesome plan ($15/month) for free if you are using a development store. Development stores can be created from your Shopify Partner Dashboard. If your store is a development store ("plan_name": "affiliate" or "partner_test"), you will see the notice You will not be billed for this test charge.

Then you can upgrade your store for free by clicking Upgrade Now. 

*Note: Make sure to activate your charge once you are upgrading your Shopify plan to a real/paid plan because otherwise, we will automatically reset your Awesome settings within 48 hours! This means you have to Upgrade to Awesome again and accept the real charge after your Shopify plan changes.
