I don't know if it's nationwide or regional, but Walgreens has Progresso soup on sale 4 for $5.00 with your Walgreens card.  Pair that with a   .50 off 2 coupon and get 4 cans of soup for $4.00!
I like to have these on hand for an after school snack on these icy-cold days, or for busy weeknights when I'm too busy to cook.
Progresso soups are very flavorful.  They've got every flavor imaginable!  Maggie likes Chicken Noodle the best, and my favorite is their High Fiber Three-Bean Chili with Beef.  What's your favorite?
