Multi Trigger Products

One offer, multiple trigger products. Tie the same add-ons to every colorway of your halter top — manage once, it reflects on each PDP automatically.

🎨

3 Widget Modes

Choose individual Add to Cart buttons, checkboxes bundled with the main product, or both. Different offers can use different modes.

📊

Offer insights

Review impressions, clicks, and cart activity per offer inside the app so you can see what shoppers engage with and adjust your setup over time.

🔄

Auto Product Sync

Add-on titles, images, prices, and variants sync automatically from Shopify. Delete a product? The widget updates instantly via webhook.

The Widget

Feels native
on the product page

The widget inherits your theme's typography and sits under the Add to Cart button. Shoppers choose add-ons in the same flow as the main product.

  • Variant selectors — customers pick exactly what they want
  • Checkbox bundle mode — add multiple add-ons with the main product in one cart action
  • Mobile responsive — looks perfect on any device or theme
  • Sold-out variants automatically disabled — no failed cart adds
  • Discount badges shown inline when you configure offers with savings
