I was in the same boat. I was completely miserable trying to keep up with it all. I decided it wasn’t worth the stress. We strictly enforce one card per person, but more importantly the 1 per shopping trip that many manufacturers say now. I also got rid of all of my sale endcaps and bulk paper. We still do daily quick picks, but only for what fits on the home location. There was a lot of pushback from customers initially, but we staid consistent about it and eventually they stopped complaining. Many of them moved on somewhere else and the few I do have left actually abide by all the rules and read their own coupons. Funny this is after doing this the entire second half of last year. My Margain, sales, and I stock all increased by a good amount. Customer service went down initially but has also started to rebound. We are so much happier now. I feel your pain, I hope you find a solution that works for your team
