It is walgreens pharmacy pushing some free stuff for you....

Received a call from a recording of a woman's voice stating it was Walgreens, wanting me to tell them my husband's date of birth. No way to connect to a live person during the call. I would never give out personal information to anyone cold calling from an unidentified number.

I called Walgreens [corporate] and they said they'd check it out.  I also reported it on the Do Not Call website.  The technician I spoke with said she thought it might be a marketing ploy.  The call was indeed about medication I take, and said it was in conjunction with the manufacturer, but that it WAS from Walgreens.  Walgreens said they don't do that type of call.  So, I reported it.
