Consumers might pay different prices depending on where and when they buy, their memberships, and a host of other factors. But what about their gender? For some goods and services, there are differences in the prices men and women pay — maybe only a few dollars or percentage points here and there, but they can add up over time. It's most often women paying more, which could be seen as doubly unfair, given the oft-cited statistic that women working full-time make only about 79 cents for every dollar men take home. But in some cases, it's men who pay a premium.
