Can PrestaShop show countdown timers, badges and savings for scheduled discounts?

Yes. When a campaign is live, Smart Dynamic & Scheduled Discounts shows the urgency cues for you on the storefront:

• a countdown timer on the product page that ticks down to the campaign end (simple, flip or circle style);
• a badge on products in category and listing pages;
• the savings shown next to the price, as a percentage and an amount;
• a campaign block in the cart.

Each of these is a separate on/off switch per campaign, so a quiet flash sale and a loud seasonal promotion can look completely different. A common slip is turning the campaign on but leaving every display option off, the discount still applies, but shoppers see no timer or badge to act on. Because the timer reads the campaign's end date, you set the dates once and the storefront keeps itself current.

In setup terms, the display record for a campaign controls show_countdown, show_badge, show_original_price and show_savings, plus badge colours, countdown style and optional custom CSS. The module has separate hooks for the product-page countdown/badge, listing badge, price-block savings and cart campaign bar, so a theme may need those hooks present or equivalent placement in the template.

The discount engine is separate from the visual layer. A valid campaign can still apply its best matching percent, amount or fixed-price discount even if the badge and timer are hidden. Conversely, no timer is shown when there is no active campaign for that product, the campaign has no remaining time, the display switch is off, or the theme does not render the hook. For merchandising, test a product page, a category listing and the cart because each uses a different storefront surface.
