I had this experience with a language learning app recently. The premium content (which I was interested in) was $30. But for the first half hour after app install the price was $20. There was a banner with a countdown timer for that 30 minutes. And lo and behold, the same banner popped up again a few days later. I don't know whether or not the technique is effective, but it sure annoys me.

I fell for it on Udemy a couple times when I was new to the site. I bought courses just in case the discount was not available when I needed it. Worked on me.

Worked, but will it again?

My mother falls for it. She gets stressed by the "sale for just X minutes more" -- eventhough I said it is mostly a scam.
