So I have a website where if users learn about my course there, they can click a button and it takes them to the course with the price they will pay for going through my website. The link is coded into that button for that particular coupon code/price, but instead it takes the user who presses the button of my website to a different, higher priced coupon code. If I manually paste the link they should be going to, it works.
What is going on?
