Want to tear that coupon out of the newspaper without ripping up the whole page? Redditor jag0007 shows us a simple method using nothing but a credit card.
Many of you may know this, but for a lot of you -- perhaps those new to coupon clipping -- might find it extremely useful: Just take your credit card (or loyalty card, or gift card), place it on your paper at an angle, and tear along the edge for a perfectly straight tear. Easy, clean, and quick. Just don't do at the checkout counter while an entire line of people is waiting behind you.
