I probably should be the last person to know this but Instagram is now allowing you to buy directly from the app so just go ahead, take all my dang money now! This is all according to Cosmopolitan.
"Today, Instagram is rolling out a new feature called "Checkout" where users can purchase items, track delivery, and receive shipping notifications directly through the app.
The social media app partnered with 20 brands for this initiative, including Nike, Zara, MAC Cosmetics, and others."
