Urgency (time limits)
Deadlines can speed up decisions, and restrictions can signal that a deal is good.
Four of the eight page areas.
Three ways to use it, and one to avoid.
- Tie sale end dates to a real outside reason, such as the end of a season, a bank holiday or the customer’s birthday.
- Show delivery cut-offs, such as “order in 2h 14m for next-day delivery”.
- Use deadlines for genuine clearances.
- Avoid: routine, arbitrary countdowns, which online shoppers tend to discount.
Purchase limits lifted shop sales. Online deadlines need a believable reason.
Online, a time-limited offer often did no better than the same offer with no deadline.
Inman and colleagues found purchase limits signal a good deal: in a grocery chain’s scanner data, featured deals with a purchase limit sold more, and lab studies found time and eligibility limits worked the same way, mainly for people who think less about the decision. Online, Hmurovic and colleagues found time-limited promotions often did no better than the same offer with no deadline, unless the deadline had a believable outside reason.
Three sources, each checked.

Fake or resetting countdown timers are unlawful: falsely stating that an offer is only available for a limited time is a banned practice under the DMCC Act 2024. The CMA secured over £4m in refunds from Wowcher (2024) and court-backed commitments from Emma Sleep over such timers.
This is simply a pointer to check, not legal advice. Seek legal advice before you put this principle into action.
