One thing I like about Blog giveaways is you know how many people have entered based on how many comments there are--so when you find one without many comments your chances of winning are good. The following giveaways I found are ending soon and have less than 50 comments (at least last time I checked).
$15 Jasmere Gift Certificate (15 comments)
Dishwasher Art (21 comments)
Deadly by Julie Cave (45 comments)
Little Looster Potty Stool (42 comments)
$100 Home Safety Kit (17 coments)
Clayful Creations (29 comments)
