Crest Announcement Bar lets you display important messages at the top of your store. Highlight shipping thresholds, flash sales, or store-wide promotions with a bar that stays visible as customers scroll. Add a countdown timer to create urgency for limited-time offers. Visitors can dismiss the bar, and their choice is remembered so it won't reappear. Every setting — text, colours, font size, padding, and timer — is managed directly in the Shopify theme editor with a live preview.
