I started using my non-disposable coffee cup about 3 weeks ago. I go get coffee just about everyday, sometimes twice, so I figure I’ve saved about 18 cups, plus the lid. I’ve also tried to stop using one time use plastic bottles. I started this 3 weeks ago. I have about 3 plastic bottles that I bring back and forth to work. I’m estimating at least 15 plastic bottles saved. That’s just me.
