DoorDash isn’t just for late-night snack runs anymore. Today, the app is running a genuinely good Sephora deal: $40 off orders of $100 or more, and it applies to pretty much everything in the store.

Here’s how it works. The deal went live at 9 a.m. ET and is open to anyone with a DashPass membership—DoorDash’s paid subscription that also gets you $0 delivery fees and lower service fees. Just use code “BEAUTY40” at checkout on a Sephora delivery order through the app (the code doesn’t work on pickup orders). Don’t have DashPass yet? You can sign up for a 30-day free trial and still snag the discount; just remember it renews at $9.99 a month if you don’t cancel.

A few things to know before you start filling your cart. The offer only works on the first 162,500 qualifying orders, so this is very much a “sooner rather than later” situation. The $40 comes off your subtotal only—so fees, taxes and tip aren’t included—and it’s capped at one use per DashPass account. That means your cart needs to hit $100 before any of those extras, so double-check your subtotal before you head to checkout. One more tip: link your Sephora Beauty Insider account to your DoorDash account, and you’ll still rack up points on the purchase.

The good news is basically everything on Sephora’s DoorDash storefront is fair game, including cult favorites from brands such as Summer Fridays, Ilia Beauty and Nars. If you’re not sure where to start, a vitamin C serum like Sunday Riley’s C.E.O. 15% Vitamin C Brightening Serum ($85) or sunscreen like Supergoop!’s Play Everyday Lotion SPF 50 ($28) are both easy wins— and together they’ll put you right over the $100 minimum.

The deal is part of DoorDash’s Summer of DashPass event and today happens to be the last day of “Sweet Treat Week,” so consider this the grand finale. Just don’t sleep on it: one-day deals like this tend to disappear fast once word gets out.
