I always join contests whenever I see one especially if it is hosted by my idols. :p
I only won once in online contests and it is hosted by GMA Facebook Fanpage. I won a Miley Cyrus Silver Ticket. I know that I won the contest through text and at first I've said to my self that I didn't enter such contest to win I thought it was a scam but later on I remember maybe it was on GMA that I've won. And it really is.
And finally"DollFace Cosmetics' Anniversary Celebration!" They have an online contest where you would have a chance to win a free seat to their Make Up Seminar by the Top Two Youtube Guru namely Ms. Noe and Ms. Janah. There are two ways to win, the first one is TAG TO WIN A SEAT TO OUR SEMINAR! and the second one is to comment in the youtube video uploaded by the Gurus and just comment Meet and Greet. I only commented on Ms. Janah's vid.
