What's better - immediate discounts or progressive discounts?

As an e-commerce store owner, I've been wrestling with the most effective discount strategy for months. Every time I blast out a flat 10% discount, I feel like I'm leaving money on the table. Some customers who were already going to buy seem to get an unnecessary price cut, while others who are hesitant just... bounce. I started noticing patterns: my dedicated buyers don't need discounts, but those on the fence require a more nuanced approach. I've seen competitors using one-size-fits-all discounts, and it feels inefficient. My gut tells me there's a smarter way to incentivize purchases without eroding my margins. I want a strategy that feels personalized, creates genuine urgency, and doesn't just train customers to wait for random sales. The challenge isn't just about giving a discount—it's about giving the right discount to the right customer at precisely the right moment. I need a method that respects my brand's value while strategically converting those wavering potential customers.
