Lea Goldman investigates gender pricing:
It's not just dry cleaning and haircuts where women get socked: We pay more for home mortgages, health insurance, and cars and car repairs (even when we mind our credit, eat right and exercise, and do our homework), not to mention everyday items like deodorant and disposable razors. California, which in 1996 became the first state to ban gender pricing, found that women paid about $1,351 annually in extra costs and fees. Apply that figure to the rest of the women in the country and the total burden is staggering — roughly $151 billion in markups.
… A recent study by researchers at the University of Central Florida examined some 200 sticks of deodorant sold at major drugstore chains and found that sticks for women cost, on average, 30 cents more per ounce than those for men, even when the only discernible difference was scent.
As far as health insurance is concerned, the ACA prohibits "gender rating," effective 2014.
