A flash sale that runs 72 hours past its intended end date due to a missed manual update is one of the most common and costly mistakes in ecommerce promotions. Auto-deactivate eliminates this risk entirely.</div></div>

This gives customers a reason to visit on weekends without permanently discounting your products. The schedule runs indefinitely until you disable it — no manual management required after initial setup.</div></div>

If your peak is 7pm–9pm, schedule the deal to start at 6pm and end at 10pm. This creates urgency within your natural high-traffic window rather than running a 24-hour deal that loses its time-pressure effect.</div></div>
