AOV $45 → $62

KartKart had healthy traffic and a low AOV that was eating their margin. In four weeks we redesigned the cart, launched bundle PDPs, and set a smart free-ship threshold — pushing AOV from $45 to $62.

The problem

What was broken

KartKart sold home goods with a $14 fulfilment cost per order. AOV had drifted down to $45 as discount-driven traffic grew. They were profitable on subscription customers but losing money on first orders. Cross-sells existed but were dumped at the bottom of the cart where 80% of users never scrolled. Email flows pushed single-product offers, not baskets.

The approach

What we did

  1. 1

    Modelled margin against AOV. Identified $58 as the break-even threshold and $62 as the target for healthy margin.

  2. 2

    Rebuilt the cart with sticky cross-sell shelf above the fold, plus a progress bar to the free-ship threshold at $65.

  3. 3

    Launched 4 bundle PDPs (kitchen starter, bath set, etc.) priced 18% below sum-of-parts.

  4. 4

    Reworked Klaviyo flows to recommend bundles, not single SKUs. Browse-abandon now sends the bundle the user almost completed.

  5. 5

    Triple Whale integration so the team sees AOV by channel daily and can pause underperforming creatives fast.

Timeline

How it unfolded

Week 1
Margin model

Break-even at $58, target $62. Sprint backlog.

Week 2
Cart rebuild

Sticky cross-sells, progress bar, free-ship threshold.

Week 3
Bundle PDPs

4 bundles live. Klaviyo flows rewritten.

Week 4
Measurement

Triple Whale, daily AOV dashboard, win locked in.

First orders went from a loss leader to a profit centre in a month. We finally stopped fearing scale.
