From what I have learned. Most customers prefer to see that they are paying the full price of what they want.
A shipping fee towards the end of a transaction tends to be a very big concern or problem for potential customers. As it is deceptive.
As the customer believes that a product is a certain price. When in reality, its a part of what they have to purchase.
I propose that once there is a way to have the currency set for people in Europe, Canada, Australia and some other countries that deem fit.
That this be integrated so that customers know the full price of what they have to pay and are not discouraged by the shipping fee towards the end.
