Quick Reference & Frequently Asked Questions
Why does a 25% flash sale discount require more than a 2x increase in sales volume to be profitable?
When you cut a $40 product by 25% (-$10.00), your landed COGS ($10.00) and fixed FBA or 3PL fulfillment fee ($6.50) remain 100% unchanged. Even after a slight drop in the 15% referral fee, your net profit per unit often drops from $17.50 to $9.00—meaning you must sell nearly 2x as many units before even counting the $150–$300 Lightning Deal entry fee.
How do Amazon Lightning Deal entry fees ($150–$500) impact small-batch promotions?
Amazon charges $150 for standard Lightning Deals and $300 to $500+ during Prime Day and Cyber Week. If your deal only sells 120 units, a $300 entry fee adds $2.50 in fixed overhead to every unit sold. Always amortize the entry fee across conservative expected deal units before submitting.
What is baseline order cannibalization during a 24-hour flash sale?
If your SKU normally sells 40 units a day at full price ($14 net profit per unit = $560/day), the first 40 units sold during your flash sale are buyers who likely would have purchased anyway—now buying at a 25% discount. Your incremental deal velocity must first pay back the margin lost on those 40 baseline orders.
When does running a break-even or slight-loss Lightning Deal still make financial sense?
Two scenarios justify a break-even flash deal: 1) Liquidating overstock before it crosses the 181-day or 271-day FBA aged-inventory surcharge cliff ($1.50 to $6.90 per cubic foot), or 2) Driving high-velocity organic keyword ranking lift on a newly launched hero SKU with strong 60-day repeat purchase LTV.
