I hate how people mix up correlation and causation with JC Penney and it’s couponless trial. The company was ALREADY very much on a fast track to bankruptcy when it decided to try removing coupons - that’s why they tried it. It didn’t make enough of a difference to pull them out of the nosedive they were in.
It’s not that not doing coupons doesn’t work, it just didn’t save a failing business.
If the sun counts as going in the house (in the form of sunlight) it also counts as touching the house (in the form of sunlight) IMHO.
