Should my retargeting ads feature a special discount to entice them back?

I've been running Meta ads and noticed something frustrating: people click through, browse my products, but then disappear without purchasing. My retargeting campaigns are costing me money, and I'm wondering if a special discount might be the magic trigger to bring them back. Every time I look at my analytics, I see these 'almost customers' who added items to cart or spent significant time on product pages but didn't convert. It feels like they're just one small nudge away from becoming paying customers. But I'm also cautious—I don't want to train my audience to always expect discounts or devalue my brand. I need a strategic approach that creates genuine urgency without looking desperate. My goal isn't just to offer a random percentage off, but to craft an offer so compelling and time-sensitive that it transforms these hesitant browsers into actual buyers. I want something sophisticated that feels personalized, not like a generic blast to everyone who ever visited my site.
