Geo-Location redirecting for IP - How could this work with different Fulfillment Locations-Currency

[Hamtin]

Hi Shopify Guru's

I'm setting up a Shopify store in the US with the stock being fulfilled via Amazon but I would like to use the same store to sell products in another country and fulfill these orders from a 3PL in that country.

I have set up the Amazon fulfillment section - but need some advice if I'm doing this correctly and mi thinking is reasonable.

I don't want to set up a completely different website as we are a very new business and I don't want to double my costs at this early stage.  Does anyone have any advice?  Do I need

 Geo-Location redirecting for IP and currency - is there a plug in-app that points to stock locations by country/market place and chooses the local currency?

Thanks
