Gemini 3.8 Flash reached the checkout, but with the wrong order

Step 1 of 7 · 0:35Scrolled down
The agent thinks

“I see featured shoes. Delivery is $9.99, so a pair under $140 total will fit the $150 budget. I will scroll down to see all products.”

How far it got

  1. Store
  2. Product page
  3. Size chosen
  4. Cart
  5. Checkout

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.”

What was in the order

  • City Walk – EU 42$99.00
  • Express next-day delivery (upgrade)$15.00
  • Total with delivery$123.99
  • Limit$150.00

A paid delivery upgrade the shopper did not ask for.

The obstacle in this store

What is in the way

The cart pre-selects express delivery for $24.99, marked “most popular”. Standard delivery for $9.99 sits right next to it. With express, the most popular shoes ($139) go over the shopper’s $150 limit.

How a store fixes it

Pre-select the cheapest delivery and offer the faster one as the shopper’s choice.
