I was at Radio Shack looking at some gizmos. I decided I wanted to purchase one of the gizmos. However, the gizmo I was looking at was a display model, taken out of the package and tied to the shelf with a security cable. I looked around, and I couldn't see these gizmos in packages available for purchasing anywhere. So I went home.

The moral of the story: If you want me to buy things in your store, make sure they are actually there.
