How Product Bundling Increased AOV by £18 for a Beauty Brand

How we designed and implemented a product bundling strategy for a UK beauty brand on Shopify Plus, raising average order value by £18 in under eight weeks.

Increasing average order value is one of the most capital-efficient ways to grow revenue. You have already paid to acquire the customer — every additional pound they spend costs you almost nothing. For a UK beauty brand on Shopify Plus, a structured bundling strategy delivered an £18 AOV uplift within eight weeks of launch.

Understanding the Opportunity

The brand had a strong hero product — a premium serum — that drove the majority of first purchases. Analysis of their order data showed that 62% of repeat customers bought the serum alongside a companion moisturiser. Yet first-time buyers almost never purchased both together. The opportunity was obvious: surface the natural pairing at the point of purchase.

Bundle Types We Implemented

  • Curated starter kits (hero product + two complements at 15% saving)
  • Build-your-own routine bundles (choose three from eight products)
  • Gifting sets with premium packaging upsell
  • Subscription bundles with additional 10% discount versus one-off

On-Page Bundle Placement

Bundle offers were surfaced in three locations: a dedicated bundles collection, a 'complete the routine' module on individual product pages, and an in-cart upsell triggered when the hero serum was added to the basket. The in-cart upsell was built using the Shopify Plus checkout extensibility toolkit, keeping everything native without a third-party app.

Key insightThe in-cart upsell for the starter kit had a 24% acceptance rate — roughly one in four customers who saw it took the offer.

Results After Eight Weeks

  • Average order value: £47 → £65 (+£18)
  • Bundle revenue as percentage of total: 38%
  • Gross margin maintained (no net discount impact at bundle volume)
  • Repeat purchase rate up 9% attributed to multi-product adoption
We always assumed customers who wanted the moisturiser would just buy it. Surfacing the pairing explicitly showed us they just needed the nudge.
