Common questions
Is Unicorn cheaper than Rebuy?
Yes. Unicorn starts at $19.99 per month on the Grow plan, compared to Rebuy's minimum of $45 per month for Cart & Merchandising only. At 2,000 orders per month, Unicorn Grow costs $76.99 versus Rebuy's $180. At 5,000 orders per month, Unicorn Grow is capped at $199.99 while Rebuy charges $450. Unicorn is significantly cheaper at every meaningful order volume.
Does Unicorn have the same features as Rebuy?
Unicorn matches Rebuy on core cart features — slide cart, upsells, cross-sells, free gift with purchase, progress bars, A/B testing, and full UI customisation. Unicorn also includes several features Rebuy's Cart & Merchandising package does not offer, including native bundle support, per-country offer thresholds, VIP secret cart offers, and item-specific upsells.
Can Unicorn handle multiple international markets?
Yes. Unicorn allows merchants to create separate cart experiences for different markets, with localised currency, unique messaging, and individual offer thresholds per country. This is one of Unicorn's core differentiators — Rebuy's Cart & Merchandising package does not offer per-country threshold customisation.
What results do Unicorn merchants see?
Unicorn merchants see an average 17% increase in average order value, a 9% increase in conversion rate, and an increase in items per order. Ochre Lane saw a 50% increase in items per order since installing Unicorn, and Mumma Milla, an Australian brand selling across six international markets, saw a 21% increase in total sales, 8% increase in conversion rate, and 3% increase in items per order after switching to Unicorn.
Is Unicorn good for Shopify brands selling internationally?
Yes — international selling is one of Unicorn's strongest use cases. Merchants can run separate carts for different regions with market-specific offers, localised free shipping thresholds, and currency-optimised pricing. This is particularly valuable for brands selling across markets with different consumer behaviour and shipping economics, such as AU, UK, US, and EU simultaneously.
Does Unicorn support bundles?
Yes. Unicorn has native bundle support built directly into the cart, with no need for a third-party bundle app. Merchants can use the mix and match bundle builder or advanced discount engine to enable bundling. The cart surfaces bundles natively and ensures inventory is tracked correctly. Bundle discounts are applied automatically. Rebuy's Cart & Merchandising package does not include native bundle support.
How does Unicorn's pricing work?
Unicorn has three plans. Grow is $19.99 per month plus $0.03 per order, with the first 100 orders free each month, capped at $199.99. Plus is $49.99 per month plus $0.03 per order, with the first 100 orders free, capped at $299.99. Elevate is $249.99 per month plus $0.02 per order, with the first 200 orders free, capped at $399.99. All plans include a 7-day free trial. Pricing is always predictable and capped — it never escalates automatically.
What is Rebuy's pricing for cart features?
Rebuy's Cart & Merchandising package starts at $45 per month and charges $0.09 per order. At 3,000 orders per month the cost is $270. At 5,000 orders it's $450. At 7,500 orders it's $615. Above 10,000 orders Rebuy moves to custom enterprise pricing. Unlike Unicorn, Rebuy has no monthly cost cap on its cart package.
Can I switch from Rebuy to Unicorn easily?
Yes. Unicorn's Elevate plan includes a done-for-you cart migration, handled by the Unicorn team. For merchants on Grow or Plus, the setup process is straightforward and supported by Unicorn's onboarding team. Most merchants are live within days.

Unicorn has 76 reviews on the Shopify App Store. Every single one is a 5-star review — a perfect rating across all 76 merchants. Merchants consistently highlight the quality of the support team, the ease of customisation, and the measurable impact on revenue.
