Congrats! I won the Loreal Mascara and did get an email. That's all I can say. You still might get it though. It happened to me with the Shaw Carpet cleaner...no confirmation email. I still have not received *any prizes. It has only been a couple weeks for most of them (2-3). I guess it takes several weeks to get.
I had to email Hertz for my confirmation and affy, no email from Loreal, but when I tried to play the next day it said I had already won..thats good enough for me.
