You know, I recently was lucky enough to win a nice chunk of change in a blog contest. I wouldn't say I spend all day entering giveaways, but sometimes a few minutes of time spent entering contests is time well spent. I know you want to win too, so here's a few links to contests that are offering pre-paid cards (cash!) or gift cards as prizes.
$50 prepaid Visa at She's Mommified - drawing after she hits 300 Google Friends
$50 prepaid Visa at Adventures in the Land of Little Choo Choos - entries close tonight at 11:59 PM
$100 prepaid Visa at Crazy Coupon Mommy - ends 8/31
$100 prepaid Visa at Busy Mom - ends 8/16
Plus, though it will take time, be sure to enter the giveaways on this roundup page!
