Show real stock counts when inventory dwindles

When to use it

When products genuinely run low or sell out but the page shows no availability signal.

How to run it

Show the actual count once inventory drops below a threshold ('Only 3 left in stock'), fed from live inventory data, never a hardcoded number.

Why it works

Give a reason to act now

Scarcity creates urgency and suggests the item must be good. Booking.com's 'Only 1 room left' and Amazon's low-stock counts work this way, though the EU forced Booking.com to clean up misleading scarcity displays.
