Guys, how to determine the selling price and delivery fee for the example below?

[micaelbandrade1]

PRODUCT on Aliexpress website	WHAT WOULD BE MY PRICE?	shipping to USA price in USD	shipping to CAN price in CAD	shipping to UK price in GBP	shipping to IRL price in EUR	shipping to AUS price in AUD	shipping to NZ price in NZD
Pack of scarf- supplier's price	?	0.99	4.32	0.82	0.95	1.57	2.77
Shipment		FREE	FREE	FREE	1.99 EUR	2.99 AUD	3.49 NZD

Friends, the example above describes the product, a package of scarves, and includes the countries I want to target. Here are the product prices when selected on AliExpress, along with the delivery fee. How would you calculate the price of the final product? Any tips on how to standardize a shipping fee or offer everything for free and add it to the final price? Or even charging the shipping fee at checkout? By the way, what mathematical formula do you use to determine the final price: supplier price x 3? 4? + shipping? Please help me out.

When it comes to delivery zones and markets, currently, I am in Australia, and on my screen, only Australia appears as domestic. What is the best strategy for configuring these two items considering the countries mentioned above and this specific product? Thank you very much in advance.
