Not the same because coupons are public and equal opportunity. It's not like you get coupons for being white or being a man, but with Uber you could actually pay less for those things. Who knows?

Coupons often come only in certain magazines or newspapers so unless you bought said newspaper you would not know of them.

Again, this is fundamentally different because the content of those coupons are not proprietary. I think we all recognize there's a difference between a dynamic price black box and a coupon.
