Mention the Increase From the Discounted Price

"Was 25% higher" is more persuasive than an equivalent discount of "20% off."

Overview

Most discounts emphasize a decrease: “Now 20% off.”

Researchers tested the reverse framing (“was X% higher”) in a Swedish grocery chain. Across products, they showed the original and sale price, yet they modified the framing:

Now 31% lower
Was 44% higher

Both magnitudes were equal, yet the latter framing — “Was X% higher” — increased daily unit sales because it depicted a larger numeral (Guha et al., 2018).
