IF the checker gives you $20 too much, that isn’t a signed contract, that is an error, and you are legally and morally obligated to return the money. Just as if they gave you $20 less, and you didn’t notice right away, you would still be entitled to your money back.
Buying a car is a negotiation. No matter what is said verbally, the signed contract supercedes that. In fact, I’d bet the contract says exactly that — the contract is the only binding agreement, and no verbal agreements have any effect of law.
If you can get the dealership to agree to sell you a car for $5600 less than the retail price, you have done well. If it happens because the dealer is an idiot, well if YOU were an idiot and paid thousands more than you needed to, the dealer wouldn’t be trying to hand you money back.
I understand. The contract negates any morality. So if there wasn’t a contract the person should pay the correct amount or return the merchandise.I agree it’s legal and binding. Just looking for the moral justification.
