I agree: This "PARCEL TRACKING NOTICE" has all the earmarks of a scam. First of all, no company is identified: not UPS, not FedEx or any other named company. Secondly, on my white postcard, they circled "Final" under "NOTICE" -- when I never received a "1st" or "2nd" notice from them. It might be worth reporting these suspicious postcards to the District Attorney's office in Martinez.
Anything you receive in the mail should be taken to the post office and forwarded to the postal inspectors. Most likely this is the "water purifier:" scam.
