One of the newer giveaway sites I have been frequenting is WinJunkie.
I was happy to win one of the first giveaways I entered on their site a few weeks ago, so I am now the proud owner of a $10 Starbucks giftcard! Now since then their contests have been getting bigger and instead of 1 a week they offer 1 nationwide contest and 1 geared towards their locals (which is Toronto, not far from me).
Why don't you go sign up and try for this weeks contests:
1 of 5 $100 Best Buy Giftcards
1 of 5 pairs of Jays Tickets (local courtesy of Fanxchange.com)
