When is 55 cents or 75 cents more than a Dollar?

Call me crazy but I get excited when I see a 55 cents or a 75 cent off coupon, or even better, although rare, an 85 cent coupon. In the coupon world, when your grocery store doubles, a 55 cent coupon becomes $1.10, 75 cents becomes $1.50 and 85 cents, you guessed it, becomes $1.70. But a dollar off coupon is still a dollar off coupon unless you have one of those stores that doubles on special occassions your coupons up to $2.00. We don't get much of those around these parts. Most stores double up to .99, but I've never seen one of those coupons. I've also never seen a buy one get two free coupon but a girl can always hope, right?
