WHICH DISCOUNT DRIVES MORE SALES, 16.5% OFF OR 17% OFF?

Summary from the TLDR Marketing newsletter

Precise percentage discounts like 16.5% often outperform round numbers like 17% in driving conversions, even when the actual value is lower. Shoppers perceive decimal discounts as more calculated and temporary, which increases urgency and purchase intent. This tactic works best when not paired with urgency copy and is more effective for functional products than luxury items.
