Some questions:
1) I’m assuming by “personalizing discount across users”, you mean personalized one-time coupon codes? I wonder if the UX of seeing one price in regular Chrome and one in incognito would be upsetting. I also don’t know how price discrimination works but seems relevant?
2) I’d love to understand more about how for smaller retailers there’ll be enough data to make meaningful discount programs for a limited set of consumers? Will data from similar/multiple retailers be bucketed?
3) Any numbers/data on effectiveness so far?
