Doubling Coupons

Whenever a coupon from the Sunday paper is worth less than $0.99, I always take them to a store that doubles the coupon. This can increase your savings by usually $0.50 to $0.75. I say this because I have yet to see a coupon worth $0.99. In the Baltimore area, I have found that the best places to take "low" value coupons is to either Giant or Superfresh. At times, usually the beginning of the month, Superfresh will have a triple coupon week. Which is when you can sometimes get items for free or virtually free.
