I have a new need from my client, We are using a plugin to detect the customer country.
The need is : the client want to have two prices one is only for US and outside US.
We created a new product attribute for outside US.
My question : How can i switch between regular price and my new attribute in frontend.
why not create two different websites?
One for the US and one for non-us.
In Magento, you can set price website wise.
Also by using Geo Ip, you can redirect website.
Hope it will work for you.
If it will help then accept as an answer.
