TikTok's price slashing idea feels more like a game than shopping

I was checking out Tiktok Power Deals yesterday and caught myself opening the app a few times just to see if the price had dropped again. That got me thinking... the interesting part isn't even the discount. It's that they turned waiting into something people want to do. You're giving people a reason to come back without constantly pushing a sale.

Made me wonder how that idea could translate to other businesses. Doesn't have to be ecommerce either. I could see restaurants, fitness apps, or even SaaS products borrowing the same kind of mechanic to keep people engaged.

How would you adapt something like this without it feeling gimmicky?
