Your grocer doesn’t sell the next person a can of beans at a different price though. Hey nice watch, we have a 50% on discount for you.

I use uber a lot, I’m in one right now. My partners phone consistently gets cheaper estimates.

Grocers run coupons and promos to help achieve price discrimination based on purchase timing preferences.

Some even have a coupon app and offer different deals to different people.

Challenge: Implement price discrimination in a setting where all prices are published on the shelf under the product without knowledge of who is viewing the price.

Possibility: Develop a "loyalty" program where customers provide a member id like a phone number at checkout. Anonymous shoppers get the worst pricing. Everybody else voluntarily signs up for price discrimination disguised as rewards.

Also the low-tech version: farmer's markets, bakeries, anything with perishables they sell daily will often give steep discounts or freebies if you show up close to closing, rewarding those that are in-the-know or are willing to modify their schedule to save some cash.

Yes they do. They even do everything they can to track me so they can optimize the coupons based on the watch I wear.
