Headsup: Announcement Popup

Closing for Christmas. Lunar New Year slowing things in one country. A supplier on strike. A payment provider down for an hour. Different problems, same task: tell the affected customers before they buy. Headsup lets you create a notice once, target it by country and date, and walk away. It shows up for affected visitors during the window, then disappears on its own. No banner-rewriting every quarter, no forgetting to take it down, no awkward customer emails after the fact.
