They need to fix this. You should not be able to plunder the coupon run. That is absolutely unfair. This amounts essentially to actual robbery. If you are a good person you would not plunder.
This is one of the worst game design decisions in the game. It basically gives a ton of coupons who the people who don't need the coupons and takes coupons away from the people who most need the coupons. That is backwards.
