Every checkout flow you have ever used is designed to be frictionless — the browse, the cart, the confirmation screen, the little rush when an order goes through.
This site keeps that entire ritual and removes exactly one thing: the part where money actually leaves your account. Add things to your cart, fill out a fake address, "pay" with a fake card, and watch a fake courier slowly make its way to a house that will never get a delivery.
Nothing here is real. That is the whole point.
