Hike Footwear added a checkout cross-sell offering orthopedic insoles at 50% off, and 1.71% of buyers took it, adding $128,223 in seven months. Hike Footwear made the change on its own store, and it was published as an Upsell.com (formerly ReConvert) case study. It launched alongside one-click upsells and thank-you page offers, and it was a before-and-after rollout, not a split test.

## Result

**1.71% take rate, $128K**

- 1.71% conversion on the checkout insole cross-sell.
- $128,223 in extra sales from the insole offer over seven months.
- $267,803 from one-click upsells and $281,121 from thank-you page offers launched at the same time.
- $677,147 in total extra sales across all three offer types, as reported by the vendor.
- 13.05% of customers accepted at least one offer across all pages.

## Control

A standard checkout with no product offers before payment.

## Variant

An in-checkout cross-sell for orthopedic insoles at half price, plus one-click upsells right after payment and offers on the thank-you page.

## Why it likely won (our reading)

- Insoles are a natural partner for shoes built around foot health, so the offer reads as helpful rather than random.
- A 50% discount gives a clear reason to add the item now instead of later.
- Spreading offers across checkout, the post-payment step and the thank-you page gave buyers several chances to say yes.
- A low take rate at checkout (1.71%) may reflect that buyers there are focused on finishing payment.

## Caveats

Before-and-after figures published by the app vendor, with no control group. Three offer types launched together, so the totals can't be credited to the checkout cross-sell alone, and the 50% discount's effect on margin isn't shared.

## How to run this test

- Hypothesis: If we offer a discounted accessory that completes the main product inside checkout, then revenue per order will rise because buyers see it as finishing the purchase they already chose.
- Primary metric: Revenue per checkout session
- Guardrail: Checkout completion rate
- Guardrail: Gross margin per order
- Guardrail: Time to complete checkout
- Who should test it: Stores with an obvious companion product, such as insoles for shoes or cases for devices. Skip it if your checkout completion rate is fragile, as any extra step there can cost full orders.
