The women's essential is currently considered a "luxury" item by Her Majesty's Government, meaning women are forced to pay an extra 5% for something they use every month.
Now the campaign to axe the tampon tax has its own theme song, thanks to Jenny Bede and Cariad Lloyd. Their expert parody of Taylor Swift's hit features a host of characters, including Madame Ovary, Jenn Da Bias, Oestro Jen and Aunti Flo.
A potato, a Soreen malt loaf and a woolen sock are all suggested in jest as possible alternatives to the "luxury" items. "You can try what you can 'til the tampon tax goes," they sing. "If it don't go soon, blood will flow."
"Initially we were just being silly but when I started looking into what doesn’t have VAT I just got really angry," Cariad told The Debrief. "It’s ridiculous and we just felt that more women should know about this, at least to start the discussion about why we are taxed in this way."
