How does one become a certified word nerd? I don't think there is a form to fill out or a test to take or a real certificate to give one the distinction; it is more of a self proclaiming certification.
I am a long time coupon user (or couponer if you want to use the industry jargon). I used them back when I was single and had a very limited budget; I used them after I got married when it was just the two of us; I used them when I quit my job to be a stay at home mom. That's almost 30 years worth of couponing (again industry jargon) experience. For a number of reasons, a few years ago, I stopped using coupons for a period of time: I was too busy; I had a couple of surgeries; I switched to more organic and natural products. Those were a few of the reasons.
