I understand that you're having trouble applying a discount and that the prices change unexpectedly at checkout. I'd like to assist you with this. To help me investigate, could you please send me a picture of what you see when you try to apply the discount code? Learn how to attach a picture by clicking this link.
Let's team up and work on this together!
