Need Help Setting up Shipping and Delivery, Duties and Taxes, and Markets

[jpp3812]

Hello Everyone,

I am new to Shopify and this is my first store. I would greatly appreciate any instructions I could get on how to set up shipping and delivery. I want to have Free Standard International Shipping and any other suggestions for rates and how to set them up are welcome.

I also need help with duties and taxes. I am just completely lost on what to do here. Do I need to set the tax for every country I want to sell in or do I just need to set it for the United States because that's where I am selling from? I have already gotten a sales tax registration id from my state and included it into my store. That's about the only thing I have been able to figure out in the duties and taxes category. As descriptive as possible for how to set this up would be greatly appreciated.

Lastly, I'm not entirely sure which markets I should set up or I have actually done it correctly. Any help I receive would be amazing. I have been trying to figure this stuff out for about a week and feel I have made no progress. 

Thank you!!
