Different areas of the U.S. seem to have different norms for couponing. In Washington state doubling coupons doesn't seem to be that common. I was at Albertsons in WA last week and in their store flyer they had four coupons you could use to double four manufacturers' coupons. The mfr coupons could be up to and including $1.00 each....so a max savings of $8.00 from the 'doublers'. I ended up getting 2 x Philadelphia cream cheese for 50 cents each and two packages of Kraft Shredded 5-cheese for $1.00. Along with the reguar coupons, I did quite well for my first try at it.
