Top 5 Free Apps for Bundle Upselling on Shopify in 2025

Why Bundle Upselling Is a Must for Shopify Stores

If you’re running a Shopify store in 2025, chances are you’re looking for smart, low-cost ways to grow your revenue without pouring more money into ads. One proven strategy? Bundle upselling. It’s simple: suggest related products, offer them together, and give your customers a reason to buy more.

According to Shopify data, merchants who use bundle or upsell apps see an average increase of 10–30% in average order value (AOV). That’s significant—and the best part is, you don’t need to pay for this boost.

In this post, we’ll explore the best free apps for bundle upselling on Shopify—starting with the most powerful, beginner-friendly solution in the market today.

1. Aero Upsell & Bundle – The #1 Free App for Bundle Upselling

When it comes to combining ease, power, and price, Aero Upsell & Bundle leads the pack. Developed by AeroApps, this all-in-one app lets you add multiple upselling strategies to your store—without slowing it down or overcomplicating your workflow.

Why it’s the best free app for bundle upselling:

• Frequently Bought Together: Suggest related products directly on product pages with custom discounts 
• Product Add-ons: Let customers select extras (like accessories or upgrades) on the product page 
• Cart Add-ons: Show relevant offers at the cart stage to catch last-minute upsells 
• Flexible Discount Engine: Offer percentage or fixed discounts, or even free shipping 
• Customizable Offers: Change headings, messages, and design to match your brand 
• Smart Shopify Integration: Seamlessly works with all Shopify themes and Shopify’s native discount system
  

Even better, Aero Upsell & Bundle is built to work right out of the box—no coding, no heavy setup. If you’re new to upselling, Aero makes it feel easy. If you’re experienced, it gives you full control without needing multiple apps.

The free plan includes:

• 1 active campaign 
• All 3 upsell types (Frequently Bought Together, Product Add-ons, Cart Add-ons) 
• Full discount control 
• Free setup and configuration support

If you’re serious about growing your store’s revenue with bundles, this is the first app you should install.

2. WideBundle – Visual Product Bundling Made Easy

WideBundle is a Shopify app that focuses more on visual product bundling. It replaces product variants with bundle options, showing them as clean, clickable buttons.

Top features:

• Creates bundles as variant options 
• Showcases bundles visually with titles and discounts 
• Easy-to-edit UI 
• Works best for single-product stores or one-page funnels

Limitations: While it has a free trial, most features are locked behind a paid plan. It’s best for stores focused on 1–3 hero products.

3. Bundler – Product Bundles by Goldendev

Bundler is a popular app that allows you to create fixed product bundles and apply discounts at checkout.

Key features:

• Build manual bundles from different products 
• Add volume discounts (e.g., buy 2, get 10% off) 
• Show bundles on product pages or landing pages 
• Customize discount types (percentage, fixed, etc.)

Why it’s worth considering: The free plan supports basic bundling, which is perfect for newer stores that just want to test bundling strategies without heavy customization.

4. ReConvert Upsell & Thank You Page

While ReConvert is mainly known for its powerful post-purchase upselling, it also offers free upsell widgets that can function as part of your bundling strategy.

Highlights:

• Add upsell offers to the order confirmation page 
• Recommend complementary products after checkout 
• Advanced targeting based on customer behavior

Use case: Combine ReConvert with another product bundler (like Aero) to increase AOV both before and after checkout.

5. UFE Cross Sell & Upsell Bundle

UFE (Upsell Funnel Engine) is another versatile app that allows you to build funnels with multiple upselling options. The free version is generous and great for testing.

Features include:

• Product page bundles 
• Cart upsell pop-ups 
• Funnels with multiple upsell/downsell steps 
• Custom design controls

Consider this if you want a visual funnel builder but don’t mind a slightly steeper learning curve than Aero’s plug-and-play experience.

What to Look for in Free Apps for Bundle Upselling

Not all free apps are created equal. Here’s what to prioritize when evaluating the best free apps for bundle upselling:

• Ease of setup: Can you get it running without a developer? 
• Performance impact: Does it slow down your store? 
• Customizability: Can you match it to your branding? 
• Discount options: Can you run fixed, percentage, or free shipping offers? 
• Support: Is there onboarding help or documentation?

This is where Aero Upsell & Bundle excels—especially for Shopify merchants in fast-growing markets. You get a flexible toolkit without worrying about hidden fees or steep learning curves.
