How to use it

Four ways to use it, and one to avoid.

  • Lead with what the shopper gets soonest.
  • Give an accurate next-day delivery promise with an order cut-off time.
  • Offer an instant discount in preference to points or a future voucher.
  • Offer spread-the-cost options with the total cost stated plainly.
  • Avoid: steering shoppers towards borrowing, as buy-now-pay-later agreements from third-party lenders became FCA-regulated credit on 15 July 2026.
What the research found

People are present-biased on average, but results vary widely between studies.

Each business day cut from delivery time raised online sales by 1.45%.

A meta-analysis of 220 estimates from 28 studies found people are present-biased on average, but with wide variation between studies and some over-reporting. The bias is weaker for money than for other rewards. At a US clothing retailer, each business day cut from delivery time raised online sales by 1.45%.

Before you use it · UK law

Delivery promises must be accurate. Buy-now-pay-later agreements from third-party lenders became FCA-regulated credit on 15 July 2026, so present them clearly and do not steer shoppers towards borrowing.

This is simply a pointer to check, not legal advice. Seek legal advice before you put this principle into action.
