Retro saturdays and coupon machines

Once a staple of grocery stores, coupon machines seem to have gone the way of paper bags(paper or plastic) they were usually red and attached to a shelf. You would pull a coupon out and then a red light would blink and another would be ready to be snatched up. I liked collecting coupons thanks to these machines even if I never purchased the products. Kids that were jerks would throw the coupons onto the floor, some machines would spit out the coupon if you waved your hand and it would drop to the floor

Bored teens would just run through the aisle and seeing how big of a mess they can make. Maybe that's why these stopped being a thing
