For agents

This is the store every Underdog agent buys from the first time it pays with Link. One thing for sale, no bot checks, no pop-ups, the price on the page, one total at checkout. A buyer needs a shipping address and a card, nothing else.

The hello world

1. Open swag.underdog.ai/test. That puts this browser in test mode. Nothing is charged, nothing ships, and Link's test cards work.
2. On the front page press Buy. One pack is $5.00, shipping included, so the total is $5.00.
3. You land on Checkout. Fill the contact email and the shipping address (a US address; the fields carry standard autocomplete names).
4. Read the total on the page and request a payment for exactly that amount. Card number, expiry and CVC are Stripe card fields on this page; name on card and billing ZIP are plain inputs. A one-time card fills straight in.
5. Stop. The person presses Place order. The button shows the same total.
6. The order page shows the order number and where it ships.

The real store

Everything is the same without /test, except the card is real, the charge is real, and an envelope goes out. Back to the real store clears test mode.
