I built a fake store to ride out shopping urges. Does this help or make it worse?

Full disclosure: this is my project. I noticed that a lot of my impulse buys were about the moment of buying, not the thing: picking it, hitting "pay", waiting for the package.

So I built Window Spree. You fill a bag, check out, get a confirmation email and track the package to your door, but nothing is charged and nothing ships. After "delivery" it asks if you still want the real thing.

I'm honestly not sure it's a good idea. It might satisfy the urge, or it might train it. That's why I'm asking people who take no-buy seriously:

• Would this help you during a no-buy, or feel like cheating?
• What would make it safer or more useful?
