The experiment, in brief

Make the value of a larger order easier to see

The challenge

Customers tended to choose a single bottle. The purchase area offered quantity control, but did not make larger supply options or their per-bottle savings easy to compare. Shoppers had to work out the value of ordering more for themselves. The task was to improve that decision without making the page feel more complicated. The choice needed to be understandable before the shopper committed to the add-to-cart action.

Working hypothesis

Presenting a small set of clearly priced supply options could make the trade-off between quantity and value easier to understand. Showing the selected option in the purchase action could also reduce uncertainty about what would enter the cart.

What changed

Wavesy introduced one-, three- and five-bottle options for one-time purchases, alongside a subscription choice. The options displayed volume discounts and per-bottle savings so shoppers could compare the offer directly. The purchase button changed with the selected bundle. Manual quantity controls moved out of the button, allowing the selector to handle the choice while the call to action handled the purchase.

The customer decision

Which supply option makes sense for me?

Show the options, make the savings clear and keep the selected order visible.

The reported outcome

The original case reports a 27% increase in average order value during the first three months. It describes more multi-bottle purchases and greater subscription uptake, but does not disclose counts or separate percentage changes for those behaviors.

How to interpret the result

The public report does not include baseline AOV, order counts, allocation or confidence intervals. Its revenue-per-visitor figure needs reconciliation with the conversion-rate description before both can be used together. Higher revenue per order does not establish higher profit per order without discount, margin and fulfillment data.

What another team can learn

Quantity offers need clear comparison, not simply a discount. Make the actual price, savings and purchase conditions understandable. In a new test, evaluate contribution margin and completed purchases alongside average order value so a larger basket does not conceal an unfavorable trade-off. These are recommended checks for future testing, not additional claims about this project.
