I'm looking for display exchange rate module, I found most of them are quite complex than what I want. I only want to display Australian dollar to Chinese yuan exchange rate at front store. Any suggestion please?
You can do this with a price layout override and some lines. To display the rate is imho just the right 3 lines. Interesting request.
Just as hint, it it a lot easier, to reuse an existing module and extend it, to show the rate. For example the cart module.
