Lotte Duty Free added Add to Cart and Restock Notification buttons to each card on its mobile Bestseller list, and the add-to-cart rate rose 45.70%. Golden Planet, an agency, ran the test with Lotte Duty Free, and it was published as a VWO case study. Shoppers no longer had to open each product page to add an item.

## Result

**+45.7% add-to-cart rate**

- Add-to-cart rate: +45.70% versus the control.
- Volume: 1,403 products were added to carts in the variant, which the team read as a sign of more multi-item baskets.
- Revenue: not reported, so it's unclear how much of the lift turned into orders.

## Control

The mobile Bestseller list showed product images and details, but shoppers had to open each product page to add it to cart, then tap Back to keep browsing.

## Variant

A separate version of the Bestseller list with Add to Cart and Restock Notification icon buttons on every product card.

## Why it likely won (our reading)

- Duty-free shoppers tend to buy several items at once, so removing a page visit per item saves a lot of taps.
- Many shoppers who opened a product page never came back to the list, so keeping them on the list kept them browsing.
- The restock button gave out-of-stock items a next step instead of a dead end.

## Caveats

The split URL test ran on 17,440 mobile users for about two weeks. Revenue and order impact were not reported.

## How to run this test

- Hypothesis: If we add an Add to Cart button to each card on our bestseller list, then shoppers will add more items because they don't have to leave the list to buy.
- Primary metric: Add-to-cart rate per list visitor
- Guardrail: Orders and revenue per visitor
- Guardrail: Cart abandonment rate
- Guardrail: Return rate for items added from the list
- Who should test it: Stores where shoppers buy several simple items in one go, like beauty, duty-free or groceries. It's less likely to help when products need a size, configuration or a close look before buying.
