These days, it feels like there is a new holiday to celebrate every day — World Dracula Day, I’m looking at you. Well, some would argue that today is another one of those days. It’s officially Pi Day.
And if you’re not familiar with the holiday, that’s okay — you don’t have to know anything about Pi to take advantage of all the deals available today. Pi Day is the annual celebration of the mathematical constant known as Pi. The holiday was founded in 1988 and it is held on March 14 as a nod to the first three numbers of Pi — 3, 1, 4. Though there are no official ways to celebrate the day, many bakeries and pizzerias have Pi Day deals. But food isn’t the only thing on sale. I scoured the internet and found 314 top deals across beauty, apparel, tech, home and kitchen and wellness, and I’m sharing the best 50 below. And while they’re not all officially connected to Pi Day, I think saving up to 64 percent on popular brands is indisputably good math. The best Pi Day beauty deals This face sunscreen from EltaMD is a favorite amongst NBC Select staffers because it’s lightweight, oil-free and contains niacinamide to nourish as it protects. It has SPF 46 and even though it is a mineral sunscreen, it doesn’t leave a white cast on skin. NBC Select updates editor Mili Godio has sensitive skin, and says this is the only formula she uses that doesn’t cause irritation. It’s also worth noting that this sunscreen has more than 53,000 five-star reviews on Amazon.
