Notice at the 14 minute mark, when I tried to qualify and ask her if she thinks it can help her, and she said "it depends", I sensed resistance.

Notice at the 25 minute mark, how I qualify and make sure she really really really wants it, BEFORE I tell her the price. I have to get her buying temperature to go up first

This makes the YES so easy and effortless.

Notice the 5 minute silence waiting for her to make payment as well.
