There's a "pink tax" involved, or a surcharge in which women are sometimes charged more than men are charged for many products.
A recent study from New York's Department of Consumer Affairs, called "From Cradle to Cane: The Cost of Being A Female Consumer," demonstrated how this is a problem that often plagues females from birth until they're senior citizens.
Here are 30 items that, according to the study, are on average more expensive for women than they are for men.
