Money of Love

So I'm watching television and the following spot comes on: A woman is teaching her husband/boyfriend how to ice skate. Anyway, he's a complete newbie, and can barely keep his feet under him. He finally makes his way over to a tree adjacent to the pond, and grabs a hold of it with one hand, while reaching in his pocket with the other. When his significant other gracefully skates over to see after him he pulls out a jewelry box and opens it. It's now HER turn to nearly plant her backside on the ice, as she literally goes weak in the knees after seeing the gift.

At the risk of sounding like a Troll (You know, Trolls are terminally un-romantic - must be that inability to survive contact with sunlight.), I have to say: "Really? Women really go weak in the knees over chain-store jewelry? C'mon, now."

I understand the overall point of the spot. But I don't understand how a bit of comic overacting is supposed to get me to drop hundreds of dollars on what is, after all, simply a nice trinket. And I really don't get how playing up the stereotype that a woman's understanding of being loved is directly proportional to the amount spent on her is at all romantic.
