Set up the shop
You say:
Make a shop on my site. I sell mugs at €12.95 and T-shirts at €24 in S, M and XL. Delivery in the UK costs €3.95. Here are the photos. Put it in test mode first.
What happens next
Your AI makes the product pages, the cart and the delivery costs. In test mode you order as if for real, without Stripe and without paying. Confirmation emails and stock already work then.
