Received a call from Medco at 6:30 pm PST, so that means that it is 9:30 pm EST in New Jersey where the call originated.  Also after "Hurricane Sandy" 5 days ago in New Jersey, I wouldn't think that they would be calling at 9:30 pm EST.  
With all that said, This is a SCAM!  Do not give out your Birthdate, phone number or address.
Don't even call them. I called back & their recording of that they are "Medco" is inaudible or hard to hear and sketchy while playing.  Even though you punch in a number to talk to someone, they are not there even 5 minutes from supposedly "Medco" after they called me.
Medco Pharmacy is a real Mail-In Order Pharmacy.  They only call you to confirm your ordered medications are going to be sent to you OR to discuss any issues with your medications that you ordered.  The real phone # for Medco is 800-841-2797.  They also have a N.J. phone that does start with (201) 891-xxxx, not the (201) 848-5078.

They claim to be Medco but I wouldn't be so sure. I've been employed at the same place for 12 years, and Medco often sends me postal mail about their services - but they have NEVER called until I got this call today. I suspect it's a scam operation using the Medco name. In any case I would never give out the kind of information they would no doubt ask me for over the phone to a caller who simply claims to be Medco, if I were inclined to sign up I would contact them myself.

Like many people have said, this is Medco. If you have prescription coverage involving them, you will often only get 3 shots at picking a med up at a pharmacy before you start paying premium pricing, so they will call you to arrange for cheaper home delivery.

Call to my home phone saying they were from Express Scripts and needed some personal info (birth date, zip code, and phone number).  She was not very well spoken, and gave me no information when I asked about a website where I could get information on the express scripts home delivery script service she said I could save money with.  There is no number listed on Express Scripts website which matches this number, and I cannot reverse look up the number as it is being reported as 'not a valid number'.  Now I'm a little worried they will call this number often.  Hoping not...
