One of the best places to get online coupons is Shortcuts.com and they just reloaded their site with $50 worth of grocery discounts. Some of the coupons include:
$1 off Wolfgang Puck soup
60 cents off Bisquick
$20 off an i-Wireless phone
50 cents off two cans of Progresso soup
$1.50 off Huggies diapers
$1 off two boxes of Chex cereal
On Shortcuts.com you can either load electronic coupons directly onto your loyalty card for a specific store, or you can print coupons at home and bring them into the store. If you take the electronic route, they will automatically apply to your bill when the cashier swipes your loyalty card.
The site has a limited number of each coupon, hence the re-loading alert. Check if there are any you are interested in before they run out.
