I completed a few surveys on-line. I received a telephone call yesterday from some lady who said she was with Profinity.com. She said I won 2 $25 gift cards for doing these surveys. She wanted me to join this and I would receive $75 more for joining. It would cost me roughly $15 to join. I told here I did not have a credit card # for her and she thanked me and hung up.
