How to make a sales promotion 25% more effective | Nudge Newsletter 🧠


Why special days work.

Promotions linked to original and appropriate special days are more effective.

Researchers in 2021 tested sales discounts with standard justification:

  • "It's our annual sale"

Vs. justification due to a special day:

People were 25% more likely to purchase from a picnic-related retailer during a "National Picnic Day Sale" compared to an "Annual One Day Sale".

So, if you're creating a sales promotion. Why not link it to a relevant day.
