Most of us either throw them away, send them to our email, save it to drive, take a picture, etc. But really, how do you manage all of your receipts? What if all receipts become email, do you think a dedicated Gmail will suffice? P.S. I also want to have many people's opinions. I saw a comment before that receipt management apps are useless, and paper is already "sustainable" with no negative environmental impact. What do you think about this?
