Limited-time discount creating urgency. Typically 24-48 hours with deep discounts.
Why It Matters
Flash sales create artificial scarcity that drives immediate action. They're effective for clearing inventory, boosting slow periods, and re-engaging dormant customers. The time pressure overcomes purchase hesitation and reduces comparison shopping.
Practical Example
Scenario
A fashion brand runs a 24-hour flash sale with 40% off select styles to clear end-of-season inventory.
Calculation
Normal day: $8,500. Flash sale day: $47,000. Inventory cleared: 850 units. Previous clearance approach (30-day markdown): Would've taken 3 weeks at similar total revenueResult
Flash sale generates concentrated revenue, faster inventory turn, and maintains full-price perception for non-sale periods.
