How do I use the Rule of 100 for my Mother's Day pricing?

Using the Rule of 100 for Mother's Day Pricing

The way you express a discount affects how large it feels to a shopper, regardless of the actual amount saved. The Rule of 100 is one of the most practical tools in pricing psychology and takes less than five minutes to apply to your Mother's Day campaign.

The Core Principle

Why This Works

Human perception of numbers is not linear. When comparing a percentage to a dollar amount, shoppers instinctively evaluate the larger-sounding number as the better deal. On a $40 product, 20 percent sounds bigger than $8 because our brains compare the numbers 20 and 8, not the underlying values. On a $200 product, $40 off sounds bigger than 20 percent because 40 outweighs 20 in the same mental shortcut.

Applying It to Your Mother's Day Campaign

• Audit your price points: Sort your Mother's Day gift products into under $100 and over $100 groups before writing any promotional copy.
• Set consistent messaging: Write all headlines, email subject lines, and product page banners using the format appropriate to each price tier.
• Test edge cases: Products priced at $95 to $105 sit at the boundary. Test both formats with your audience to determine which converts better for your specific customer base.
• Bundles: When promoting a bundle, show the total dollar savings rather than a percentage because bundle prices often exceed $100 and a dollar figure is more concrete.
