4. Take control of in-cart discounts with the Tiered Progress Bar powered by Shopify Functions

New updates to Rebuy Smart Cart’s Tiered Progress Bar give you more control over your in-cart discounting. With the deprecation of Shopify Scripts coming August 2025, our latest update introduces Shopify Functions for a more seamless discount setup.

1. Improved Discount Options: You can now choose between using Scripts or Shopify Functions for discounts. Functions support a wider range of discount tiers, including free products, free shipping, and percentage or dollar discounts.

2. Enhanced Customization: You can now select between a default icon or a product image for free product tiers, adjust icon sizes, and customize tier labels and texts for a more personalized cart experience.

3. Automated Shopify Functions: Now, Rebuy Smart Cart automatically generates a new Shopify Function based on the discounts you set in the Rebuy admin, streamlining the setup process and reducing manual configuration.

These updates are designed to give you greater control over your cart promotions and make it easier to create engaging, dynamic shopping experiences for your customers.

ℹ️ Using Shopify Plus? Here's how to migrate from Shopify scripts to Shopify Functions.

You can add up to four reward tiers to the Tiered Progress Bar. Select among three reward types (free shipping, free product, and discount) and between two discount types (percentage and fixed dollar amount).

5. Optimize the cart experience with A/B Testing for Smart Cart

Rebuy’s new A/B Testing for Smart Cart takes optimization to the next level by allowing you to test different Smart Cart configurations seamlessly. This feature empowers merchants to test two Smart Cart variations to see which performs best. You can even compare your Rebuy Smart Cart to a non-Rebuy cart.

Here’s how it works:

• Easy Setup: No need for Javascript or complex setups when testing your shopping carts—just use Rebuy’s A/B testing tool.
• 50/50 Split: See both segment cohorts for a true apples-to-apples comparison. Split the audience 50/50 or adjust as you like.
• Schedule Test for Later or Start Today: Schedule your experiment for later or launch today.
• End Experiment: Once your test concludes, you can set the winning Smart Cart live automatically or leave it unchanged.
• View-Only Experiments: During testing, Smart Cart experiments are view-only, preventing any interference with live carts.
• Data-driven Experimentation: Rebuy monitors each session from every cohort, tracking session conversions, generated revenue, and revenue per user.

This new feature simplifies the testing process and makes it easier for you to “try before you buy” by testing different Smart Cart configurations with minimal risk.
