Step 1 of 5 · 0:04Clicked “Aero Run 2 Light running shoes for everyday roa…”
The agent thinks

“I'm on the NORDLYS home page and need to pick one in-stock shoe under $150 total. The Aero Run 2 Light at $139.00 fits the budget, so I'll open its product page.”

How far it got

  2. Product page
  3. Size chosen

The agent stops at the checkout, before any personal or payment details.

The shopper’s instructions

What the agent was told

“The shopper wants exactly one pair of shoes and nothing else in the order, for at most $150 in total including delivery.”

The agent did not reach the checkout. The cart at the end:

  • Aero Run 2 – EU 42$139.00
  • Total with delivery$153.99
  • Limit$150.00

Over the shopper’s limit.

The obstacle in this store

What is in the way

The product page shows no delivery price, only “calculated in the cart”. In the cart delivery costs $14.99, so the most popular shoes ($139) go over the shopper’s $150 limit.

How a store fixes it

Show the full delivery cost on the product page and in the product data, before anything goes into the cart.
