Scam Alert
I got this in the mail yesterday, and smelled a scam. I've recently ordered a lot of books on line, but knew they would be coming to me via the USPS or other carriers I've heard of.
I Googled the "delivery service" and, lo and behold, it is a scam. Apparently you call the number and they try to sell you a "free" vacation. The no-call list means these scammers can no longer call you (well, not legally), so they have to try and get you to call them. Beware, and, if you get one of these in the mail, just throw it out.
