My example:
People who purchase warranties that cost more than the item they want to protect is worth. I noticed this recently when picking up another usb flash stick a while back. The device doesn't have a failure rate that's particularly high and the warranty would expire long before anything wear-n-tear wise would happen. It also didn't cover accidental damage and cost just a few dollars less than the device. By the time I would need to replace it, my device would be worth significantly less for the same amount of storage. The price I paid then would provide more storage for a better device and I couldn't use the warranty to get a newer model if it happened. I guess they were trying to play on some kind of security/comfort need?
