You say:
Make a store on my site. I sell mugs for €16.95 and T-shirts for €29 in S, M and XL. Shipping in the US costs €5.95. Here are the photos. Put it in test mode first.

Your AI makes the product pages, the cart and the shipping costs. In test mode you order as if for real, without Stripe and without paying. Confirmation emails and stock already work then.
