You may have heard of the so-called “pink tax,” where female-oriented items such as razors, deodorant and soaps, even if they are mostly identical to a male version, will carry a higher price tag. But it isn’t only grooming products that are unfairly impacting women’s wallets — there’s a “tampon tax” too.

This summer, New York became the 11th state in the nation to not apply a sales tax on tampons and pads. But for the rest of the country, these products are taxed because they are considered “luxury items,” and not necessities such as food, clothing and other medical products. Some of the items that fall under the medical products umbrella that were exempt from the tax included chapstick, Rogaine and shampoo.

But this week, in an effort to raise awareness about the pink tax, 3-year-old bulk shopping startup Boxed.com will begin offering discounted women’s personal care items when the price is higher than the equivalent men’s products, and discounting pads and tampons by 9 percent.

The company found that on average, per ounce, women are paying 167 percent more than male consumers for a bar of soap, 108 percent more for razors, 10 percent more for body wash, 8 percent more for deodorant and 5 percent more for shaving cream.

As for how the move might impact the company’s bottom line, Boxed CEO and co-founder Chieh Huang says that “We’re in a unique position, because we ship on average 9.8 items to the typical consumer. So if we take away a margin on one or two items, you have close to eight other items that we’re making a decent margin on to make up for the loss,” he says. “It’s a no-brainer. It’s just the right thing to do.”
