I want payment for all this to be base on user's country currency . If my user is in the US, they pay $19/month; if in China, they pay some other rate. So, I am thinking I could detect the user's location,

Then system will auto assign the location or country  to their profile, and from their location, System can detect their currency (via a location to currency map table in my database). then system will auto assign it and all payment will be displayed in their currency.

buy store product in their currency.

Pay for ads or feature in their currency.

Search for classified item in their selected currency
