text: Hi, Can someone assist me with adding on the thrid party shipping option, it states that you can add on this option for an additional 20 USD however im finding it impossible to find and upgrade my package with this option ?
  The carrier calculated shipping feature is available in the Shopify lite plan. You can check more details here: https://help.shopify.com/en/manual/intro-to-shopify/pricing-plans/plan-features#shopify-lite-plan.
  To add the feature, you will have to contact Shopify support (faster response via chat).
  Hi, @lifexpanded! Yes, you can definitely get Carrier Calculated Shipping added to your Lite plan. This will allow you to offer shipping rates from your chosen shipping rate provider (usually 3rd party).
  To get that added, just reach out to our live support as it won't be visible on your admin to add that in there.
  Since you're using a 3rd party shipping rate provider, it could be beneficial to consider planning out some shipping options to increase conversions for your store. Take a peek at our blog for using a flat rate shipping strategy to incentivize higher sales.
