Oh god, I did it. I was good at it too, I could get $200.00 worth of groceries for $14.00 regularly-my best was $400 for 17.00. (I got applause). I could read the coupon bar labels so I know what the coupon was really good for (not always what it says in writing). Some coupons are good for anything in the store, even though it says Monostat 7 on itor something. I went way,way overboard. I'd have 50 coupons a trip, knew which stacked, doubled, etc.
To my (hopefully) credit, I always shopped at 7:30 am when the store was empty and I always warned anybody not to get behind me as it would be slow. If they had one clerk (rare) I'd ask for a manager.
A shopping trip could take two hours. You have to read everything-you aren't buying for what you need, but for what you can get for pennies. You store it and eventually you don't need to go to the store, you have everything.
I finally realized it was a stupid hobby when I had more barbecue sauce, pasta, salad dressing,TP and tooth paste than I could use in years, and I was running out of places to store it. Unlike Mama June, I didn't want shelves of product everywhere. Plus, I wasn't poor, I was a hobby. I did donate to shelters but they were not so interested in sauces as they were toothpaste. It was a full time job to sort coupons, plan your trip, know the stores revolving sales, when certain items would go on sale, etc. for a while, I wasn't working so it was ok but when I started working it was too much.
It took a full year after I gave it up to stop feeling guilty for spending money at the grocery store though.
This feels like powerleveling but you asked..I considered it a busy time in my life. It was a hobby, I got good at it but it wasn't fun after a while, it became work and I'm not fond of work as a hobby! Now I just spend my money like a normal person. The guilt is gone and I have no desire to do it again.
But I know how it works, so that's a plus....?
