My experience with acbuy coupons for adidas

Quick question for the community - I'm trying to use acbuy's coupons feature but running into some issues. I've followed the guides I found but something isn't clicking. Specifically, I'm trying to order air jordan and the process seems different from what others have described. Has anyone else encountered this? The interface looks different from the screenshots I've seen. I've already tried clearing my cache and using a different browser. Same result. Any suggestions would be really appreciated. I've been stuck on this for 69 hours now. Thanks in advance!
