When a person clicks on our links, it will still show a green bar at the top with "20% off your first order. Code BLABLA applied."
Only when they input the code on the checkout page, they see it's actually 30% off.
That green bar with this 20% off message at the top needs to be upgraded also somehow on the backend.
Otherwise, people will arrive, see the 20% off with our code and then see immediately next to the green bar, the 30% off USA30 code. And they will switch it thinking our codes are 20% and that one is 30%.
Just some feedback. If you can fix it, it will be great.
