CVS drugstore is known for having seriously long receipts—some receipts could measure out to the length of an adult human or a couch. A recently published Vox article also points out that CVS receipts have their own witty memes on social media.  

But all kidding aside, how much paper does the company waste printing out these lengthy receipts? Back in August, nonprofit Green America launched a “Skip the Slip, CVS” campaign, urging the company to change its receipt practices. And a couple years ago, CVS implemented a digital option for customers who didn’t want paper receipts.

According to Vox, since introducing the digital option, CVS says it has saved “more than 3 billion inches of paper,” which translates into 47,348 miles.

(You can join as long as you are willing to turn over your name and phone number in exchange for better deals.)
