Microsoft manufactured a defective product and Best Buy sold it to me. It RRoD'd 6 months after I bought it. They had extended the warranty to 3 years by then, but why should I be out a 360 for 30 days?

Would you drive a car that spent 30 days in the shop every 6 months without a rental?

You get the box and all packaging, and you send only the unit with no drive. That allows you to buy a new one from the store, put your drive on it with your Tag and save games, then return it for a refund when your refurb is shipped back.
