When paying bills online, instead of printing out the confirmation page, take a screenshot of it. You’ll save the cost of paper and toner, and you’ll save the environment at the same time (and save yourself from having to shred the paper later on).
I discovered this tip by necessity because my computer isn’t hooked up to a printer (I use Marc’s computer when I need to print) and it’s always bothered me that I haven’t been printing all of the confirmation pages (not that it’s been a problem, but I’m compulsive that way).
Get Screengrab for Firefox here. (Note: I couldn’t find a free version for Explorer.)
P.S. If you’re not paying your bills online yet, what are you waiting for? It saves time and money and is super easy to do!
