Whenever I see or hear the words, IT'S FREE! Or BUY ONE AND GET ONE FREE! I'm all over it. Of course, if it isn't something I can't use or no one I know can use, I won't get it, but most likely I'll try it. My grocery store has those type of sales all the time and I love it. It especially comes in handy with me having a college student. She gets the second one. :-)
I ran a little contest over at Romance Magicians and I was surprised how few of the chapter members commented. I can tell you if someone in the four chapters I'm part of said they were giving away gift certificates, I would be all over it, trying to win one. LOL! Oh, well, live and learn.
