Smaller Sale Prices on Product Pages Show a 3.0% Conversion Rate Lift


If the discounted price is shown in a smaller font than the original price, then conversion rate on sale items will increase because smaller text makes the price feel lower.
What We Changed
- Showed the discounted price in a smaller font than the original price.
- Applied the new price styling to product pages and product cards.
- Kept the original price struck through next to the sale price.
