Like FTC, I estimate that banning these would save U.S. consumers millions of hours they currently spend searching and clicking on pointless coupons on their phones before making purchases. It would also increase happiness, as it's extremely annoying to pay $20 extra, knowing that a lower price is available if only you spent ten minutes struggling with a store's website on your phone.
Whoever invented this is evil and is destroying happiness.

Even better: for political candidates!
