Redirect to our another store during checkout

4 0 0

Hello guys,

We are facing a very uncommon problem. 

We have 2 websites, EU store and US store. 
And a Facebook shop.

The Facebook product link directly points to the US Store Checkout page. 
And we want to redirect visitors to our EU Store if they're in EU, from the checkout page. 

Is there any way we can detect the visitor location then send them to the EU store?
I am aware that we can't add Javascript and even no App can work on the Checkout page. 

Just wanted to make sure, is there any workaround in this case?
Maybe we could have a bridge between FB and our Stores, a script that detects location and sends visitors to whether EU or US store, but it'll add another web page. 

Thank you in advance,
