Tom needs a couple of things, including a new sleeping bag for his trip to the snow. When the salesclerk in the store approached Tom, this following conversation occurred:

Salesclerk: Do you need any help.

Tom: Yeah, I do. Some friends are going camping next week. I need a sleeping bag that is waterproof and good to -10 degrees. I also need new hiking boots to go hiking in the snow.

Salesclerk: Okay, We have two waterproof sleeping bags in stock. The temp 300 and the fortitude 9.3. The temp 300 is made from a tech material with polyester filling and the fortitude 9.3 has down filling. The temp 300 is $400 and the fortitude 9.3 is $800. It is a luxury product.

Tom: That is a bit more than I was looking to spend.

Salesclerk: I have one more, it's a display item. It's going cheap for $200. Let's have a look at it.

They go over to look at the sleeping bag. Tom is pretty happy with it and agrees to buy it.

A week later, after a very cold trip in the mountain, Tom returns to the store very angry. As it turns out the sleeping bad was not waterproof. In fact, he spends most of the week very wet and had to share a sleeping bag with a friend. He has also done some research online and discovered that the sleeping bag is not good to -10 degrees.
