If you’ve ever bought envelopes in college, you know how stupid it feels. You use about two per year. Why buy a box of 40 for way too much money from the bookstore? 

Instead, plan ahead by saving the envelopes included with your bills that you’d usually discard. Everything from your student account bills to junk mail will provide you with a blank envelope and most just have windows — no address or anything. They’re good as new. You’re probably not using them, especially if you pay bills online. 

Plus, the whole process is also a great testament to reuse. You might be wasting paper by opting out of an electronic bill — according to your bank’s incessant notifications — but at least you’re putting their envelopes to good use. Now that’s what I call PUSHING THE ENVELOPE. HA!
