While October Prime Day has yet to kick off, there are plenty of juicy deals already available on Amazon.

Under-the-radar scores include 15% off Tarte Maracuja Juicy Lip Plump, a viral beauty buy that’s earned even Sarah Jessica Parker’s stamp of approval.

It seems the “Sex and the City” star couldn’t help but wonder about the formula, as she wrote on Instagram that she discovered it from her go-to makeup artist, Elaine Offers Woulard.

“I am not an influencer, I am just the ‘appliquee,’” Parker quipped in her post, raving, “Oh Tarte, what have you done?”

The formula comes in 10 glossy shades, ranging from white peach to deep mauve.

Parker’s far from the only one obsessed with the product; according to the brand, one flies off the shelves every six seconds. (Not to mention, it’s the No. 1 bestseller in Amazon’s “lip plumping treatment” category right now.)

“I can’t believe how amazing this stuff is???” one five-star reviewer writes. “I put it on, and my jaw dropped.”

A second satisfied shopper called it “not sticky at all,” while a third said it “glides on like a 90s movie heroine’s lipstick would.”

Tarte’s Shape Tape Concealer also has a long list of celebrity fans.

Shay Mitchell once told Cosmopolitan UK the product is “something that I live by,” while Kyle Richards gushed to E! that she “doesn’t know” what she’d do without it.

Whichever product you’re shopping, be sure to do so fast before these deals disappear.
