Thank you for your comment! If Google thinks I'm interested in Grammarly, it is sadly mistaken. And those ads show up when I'm home (I don't watch videos from work (!)), so the only way it'd figure out I'm affiliated with a university would be because I sometimes have my email or the course management software (both sites ending in .edu) open in the same web browser. All that talk about artificial intelligence, and Google can't even tell it's been showing me the same ad I don't care about dozens and dozens of times. You're right that Grammarly may not be aware that its marketing budget is being used to show the same one ad to the same customers again and again. It must still represent a sizable amount of money and I'm impressed they found the cash given that they operate on a freemium business model. It's hard not to get the impression they are throwing money at advertising to generate a critical mass of users, and it's even worse if their money is being wasted on the same viewers, and viewers like me who don't even want Grammarly.

And I also think Amazon should have a feature to rate deliveries, especially now that it has its own delivery services in some cities, so that there would be a way for it to know if a delivery man keeps delivering packages to wrong addresses, etc. But of course Amazon doesn't care, because it thinks the last mile is to deliver to the parcel locker. It's time to find for me to buy from Barnes & Noble again.
