FAST Bundles: Quantity Breaks
shopify quantity breaks app
Boost average order value with bundles, BOGO and volume discounts.
The problem
Acquiring a customer is the expensive part; selling them a second unit is not. Yet most stores present one product at one price and leave the rest to chance. Native Shopify discounts can cut a price, but they cannot say 'buy three and save 15%' on the product page where the decision is made, and they cannot let a shopper assemble their own box.
How it works
Pick an offer type
Quantity breaks for tiered pricing, a fixed bundle for a curated set, or build-your-own-box for mix-and-match. Or let the AI suggest bundles from what is already selling together.
Choose products and tiers
Select the products or collections, then set your tiers — buy 2 save 10%, buy 3 save 15%. Inventory and currency stay in sync automatically.
Publish to your theme
The widget renders on the product page in your store's styling. Discounts apply at checkout without a code for the shopper to remember.
What you get
Tiered volume discounts
Set as many quantity breaks as you need, with percentage or fixed-amount savings, displayed clearly at the point of decision.
Build-your-own-bundle
Let shoppers assemble a box from a defined set. Ideal for consumables, samplers and gift sets where choice is the selling point.
Fixed bundles
Curate a set of products and sell it as one offer, with its own pricing and presentation.
AI bundle suggestions
The app reads your catalogue and order history and proposes bundles that reflect what customers already buy together.
Multi-currency and inventory sync
Prices convert correctly for international shoppers, and bundle stock tracks the underlying variants so you cannot oversell.

“The Mix & Match feature seamlessly integrates with my Shopify. This is the bundle sale implementation that I have been looking for. The support behind this app are so responsive and helpful. They even provided a loom video to help me understand how I can implement the feature on my store. I have already recommended this to other ecomm business owner.”

“Fantastic App with Excellent Support This app works exactly as expected—clean design, efficient performance, and overall a great user experience. I had a small cosmetic issue due to the custom theme I use, but Ori from customer service was incredibly responsive and resolved it within 24 hours. Really impressed with both the app and the support team. Highly recommend!”

Questions about FAST Bundles
Do bundle discounts work with my existing Shopify discounts?
Bundle pricing applies at checkout. Whether it stacks with another automatic discount depends on your Shopify discount combination settings, which you control.
Will it match my theme?
The widget inherits your typography and colours and exposes its own styling controls, so it reads as part of the product page rather than an embed.
What happens to inventory when someone buys a bundle?
Stock is drawn from the underlying variants, so your inventory stays accurate and you cannot oversell a component.
Does it support multiple currencies?
Yes. Bundle prices convert using your Shopify Markets configuration, so international shoppers see correct local pricing.
What counts toward the $600 free limit?
Only revenue from orders that actually included a bundle or quantity break. Ordinary orders never count against it.
