How do I prevent discount abuse from serial abandoners?

Look, I'm frustrated. Every time I run a discount campaign, I see the same pattern: some customers game the system. They add items to the cart, abandon it, wait for a discount code, and then purchase. It's like they've turned my promotions into a predictable discount hunting game. My margins are getting squeezed, and these serial cart abandoners are essentially training themselves to never pay full price. I've tried generic solutions like limiting discount codes, but nothing feels precise. I want a way to offer strategic, personalized discounts that reward genuine buyer intent, not professional discount hunters. My goal isn't to punish customers but to create a smart system that understands who's truly interested in my products versus who's just waiting to exploit a promotion. I need a solution that can differentiate between a hesitant buyer who might need a gentle nudge and a serial abandoner who's systematically working the system. My business runs on trust and smart marketing, and right now, these discount tactics feel like they're eroding both.
