A Nickel or a Dime
Like when you think you're getting a deal, but it turns out you're paying extra for everything and it's all hidden fees.
"That car costs $20,000, and then there are all these extra fees.", Me, after being scammed by a dealer
"You think you're getting a good deal? That’s just a bunch of hidden fees.", My mom, after I bought a phone
"You paid $100 for a car, but it's all hidden fees.", My brother, after he got scammed"
