Upsells and cross-sells are one of the quickest ways to raise average order value without buying more traffic. Rebuy is one of the best-known personalization tools for Shopify, but it costs more than a simple cart-drawer app, and its pricing scales with your order volume. This Rebuy app review covers what it does, how much it costs, how to set it up, where it falls short, and which stores should look at lighter alternatives.
Details come from Rebuy’s Shopify App Store listing and its pricing page, checked on October 9, 2026. Pricing and ratings change, so check them again before you decide.
Rebuy App Review: Quick Verdict
Rebuy is a strong fit for DTC brands that want one platform for cart upsells, bundles, post-purchase offers, search, and A/B testing. It’s a poor fit for small stores that only need a basic slide cart with a free-shipping bar.
- Best for: Stores with steady orders, a team to run tests, and a goal of raising AOV across the whole journey.
- Skip it if: You want a simple, low-cost upsell bar, or you dislike pricing that rises with order volume.
- Rating: 4.7 stars from 854 reviews on the Shopify App Store.
- Starting price: From $25 per month for one package, scaling with orders per month.
- Free trial: 14 days for packages and 30 days for Platform One.

What Is Rebuy?
Rebuy Personalization Engine is a Shopify app that adds AI-powered product recommendations, upsells, cross-sells, bundles, search, and merchandising across the shopping journey. The listing describes it as covering the cart, checkout, post-purchase pages, and search.
It’s organized into four packages: Cart & Merchandising, Checkout & Post-Purchase, Search & Collections, and Flows & A/B Testing. A free add-on called Rebuy Monetize is included with every plan. A rules engine mixes conditional logic with AI recommendations, so you can control what appears and when.
Who Rebuy Is For (and Who It Isn’t)
A Good Fit If You…
- Run a DTC store with steady orders and want to raise AOV and items per order.
- Want one platform instead of separate cart, bundle, and post-purchase apps.
- Want to A/B test recommendations instead of guessing.
- Use tools like Recharge or Klaviyo and want them connected.
- Are on Shopify Plus and want upsells inside checkout.
Look Elsewhere If You…
- Only need a slide cart with a free-shipping progress bar.
- Have low order volume and a tight budget.
- Don’t have time to set up rules and run tests.
- Prefer flat monthly pricing that doesn’t grow with orders.

Rebuy Pricing and Plans (as of October 9, 2026)
| Option | Price | What you get |
|---|---|---|
| Development stores | Free | For development stores |
| Rebuy Monetize | Free | Offers on thank-you pages; Rebuy estimates $0.20 to $0.35+ per order |
| Build your own plan | From $25/month for one package | Pick packages à la carte; price scales with orders per month; 14-day trial |
| Premium Support add-on | $499/month | Priority support, a Customer Success Manager, quarterly business reviews |
| Platform One | $534/month shown at the default order volume | All packages, premium support, dedicated CSM, beta access, discounts; 30-day trial |
Charges are billed in USD. Rebuy lists a discount when you bundle packages and a 10% saving on annual billing.
How the Pricing Works
Price depends on your orders per month. Rebuy’s pricing page has an order-volume slider, so the number you see changes with your store. Billing runs on a 30-day cycle based on the previous 30 days of metrics, and your first invoice follows your store’s order count and tier. Use the slider with your real order count before you decide.
ROI Guarantee and Refunds
Rebuy says it guarantees a positive return, measured as the extra revenue Rebuy drives compared with what you spend on the platform. Refund requests must be made within 60 days of billing, and a refund isn’t issued for simply not using the product. Read the terms before you rely on the guarantee.
Is It Worth the Cost?
Do a quick break-even check. These numbers are illustrative, not Rebuy’s pricing:
| Item | Example |
|---|---|
| Orders per month | 1,000 |
| Average order value | $60 |
| Monthly revenue | $60,000 |
| Gross margin | 50% |
| Example monthly bill | $300 |
| Extra revenue needed to cover the bill | $600 |
| Lift needed | 1% of revenue |
Use your own bill, margin, and order count. If a small AOV lift covers the cost, the math works. If not, a cheaper app may be a better fit.
How to Set Up Rebuy (Step by Step)
1. Record Your Baseline
Note your current AOV, conversion rate, and items per order. You’ll need them to judge whether Rebuy helps.
2. Start With One Package
Begin with Cart & Merchandising and the free trial. Add more packages only after you see results.
3. Install and Review Permissions
Install Rebuy from the Shopify App Store. The listing asks for broad access, including customer, order, discount, theme, and checkout data, so read the data access list first.
4. Set Up Smart Cart and Widgets
Configure the slide-out cart and your upsell and cross-sell widgets. Match the styling to your theme.
5. Add Rules
Use the rules engine to control what gets recommended. For example, exclude low-margin or out-of-stock products from upsells.
6. Test One Change at a Time
Run A/B tests, which sit in the Flows & A/B Testing package. Change one thing per test so you know what caused the result.
7. Check Speed and Mobile
Test your product pages and cart on a phone before and after installing, and compare the results.
8. Review After a Few Weeks
Compare your AOV and conversion rate to your baseline, and compare the lift to your bill. Remember the 60-day refund window.

Rebuy vs Other Upsell Apps
| App | Price | Rating | Built for Shopify badge | What the listing says |
|---|---|---|---|---|
| Rebuy | Free for dev stores; paid from $25/month | 4.7 (854) | Not shown on listing | AI recommendations across cart, checkout, post-purchase, search |
| Upcart | Free plan available | 4.7 (957) | Yes | Slide cart, reward bar, upsell cart, free gifts |
| Kaching Cart Drawer Cart Upsell | Free plan available | 5.0 (1,462) | Yes | Slide cart, upsell cart, free-shipping bar |

When a Lighter App Makes Sense
If your goal is a slide cart with a shipping bar and a few upsell offers, one of the cart-focused apps above may cover it at a lower cost. Compare their feature lists against what you need before paying more.
When Rebuy Makes More Sense
If you want recommendations across the whole journey, post-purchase offers, search, and unlimited A/B testing in one place, Rebuy covers more ground. It’s also worth a look if you want upsells tied to your subscription or email tools.
Limitations and Things to Watch
Costs Grow With Orders
Reviewers point out that usage-based pricing rises as your order volume does. Model the cost at your current volume and at twice that volume.
Attributed Revenue Isn’t the Same as Extra Revenue
Rebuy reports revenue it drives directly through its widgets and recommendations. Some of those sales might have happened anyway. Use A/B tests or a holdout group to measure real lift.
Speed and Theme Conflicts
Apps that add cart and checkout widgets can affect page speed. Merging several apps into one can help, but test it. One third-party review also mentions minor bugs with certain themes.
Permissions
The access list is extensive. Make sure you’re comfortable with it, and limit staff accounts that can install apps.
Rebuy Monetize Shows Other Brands’ Offers
Monetize puts third-party offers on your thank-you page. Check that the offers fit your brand, and adjust the settings.
Which Rebuy Setup Fits Your Store?
| Store type | Suggested starting point | Why |
|---|---|---|
| Small store, simple upsells | A lighter cart app, or one Rebuy package at a low order tier | Keeps costs down |
| Growing DTC brand with steady orders | Cart & Merchandising, then add packages | Start with the biggest AOV lever |
| Subscription store (Recharge, etc.) | Check the integration, then test | Rebuy lists these integrations |
| Shopify Plus brand | Add Checkout & Post-Purchase | Checkout Extensions need Plus |
| Larger brand wanting support | Platform One | Includes premium support and a dedicated CSM |
| Any store wanting extra revenue | Rebuy Monetize | Free; check brand fit |
What Merchants Say
On the Shopify App Store, 806 of 854 reviews are five stars. Merchants commonly say it raises AOV, units per order, and conversion, and that it replaces several separate apps. Many single out the customer success team. Low-star reviews exist too, so read them to see which complaints match your situation.
Final Verdict
Rebuy is one of the most complete personalization and upsell platforms for Shopify. If you have steady orders and want recommendations across the cart, checkout, and post-purchase pages with A/B testing, it’s a strong candidate. Whether it’s “the best” depends on your size and budget. For a basic cart upsell, a cheaper app may be enough.
Before you commit, run the free trial with one package, record your baseline, and measure lift against your bill.
