How can I automatically include shipping costs in my retail price?

[EDestruction]

Hello, I have a question about shipping rates being added to the total retail price. I am using Printify to make some products however I made the shipping free and would rather include it within the price. Until now I have been manually calculating my profit margin of the original product cost plus the shipping rate I was wondering if there was a way to automatically calculate both the product cost and shipping rate together to more easily determine how much I need to charge for profit and the total product retail sale cost. Thank you for the assistance.
