Buy at the time of order, or within 30 days of your machine purchase.
One extended warranty product adds a 2nd year of cover.
You can buy it at the time you order your machine, or any time within 30 days of your machine purchase date. After 30 days, it can no longer be bought. This 30-day window runs from your original machine purchase date, so a replacement machine does not reopen it.
If you already hold a 3-year extended warranty on your Clean, you keep that cover in full.
Extended warranties are never discounted on any channel.
