All of the products in our demo store are triggers for the post-purchase upsell— which offers the Geometric Earrings during checkout.
In this case you can put through a test order to see how it all works. Add any item to an order, then click ‘Checkout.' You can fill in any shipping and billing information, and in the payment fields use the following:
Credit card number: 1
Name: any first name and last name
Expiry date: any date in the future
Once the order goes through you will see the offer page!
