User would be customer or the business owner? Sorry for the confusion..
an example of what I am talking about is that the customer purchases in their local currency and when the transaction is complete it is the currency of the business owner as a pay out.
Additionally, I saw on the post that there is the ability with your plug-in to have a hidden value in in whatever currency i.e GBP as a basis for the price and i.e. Euros that would go to the customers cart as Euros.
Thanks for your reply
