Lately there have been a pretty sizable amount of discount codes coming in both my virtual and physical mailboxes.
Just now, it hit me as to how to keep them all in one place without going from one email to another, or sifting though plies of paper.
Use Evernote (aff link).
I separated the discount codes by Professional and Personal so that I can easily know where to go to pick up a specific coupon code.
So whenever I run across a code that I think I might need later, I just copy and paste the code to Evernote, and I’m good to go.
