Chirpify is an in-stream social commerce platform that, up until now, has enabled brands and businesses to allow customers to buy, sell, donate and exchange funds without leaving Twitter. Now the platform has expanded its reach into Instagram. Users who sign up with Chirpify and have input their PayPal and shipping information can simply find items being sold on Instagram, which are marked with “#instasale” and the dollar amount of the product. If they want to buy the item, they can enter the word “buy” in the comments for an instant transaction. Users who want to donate to a cause can comment with the word “donate.” (The Next Web, TechCrunch)
