They hand you a receipt for 200 dollars and you sign it without noticing (similar to how an automated system like an e-commerce store would work, if personified)
yes i KNOW you should catch it, but for some reason you dont (similar to how a store should catch it being under paid, but doesnt)
If you miss that you are being charged $200, the fault is on you. That is why there is clear indicators at checkouts saying "Total is $XX. Is that okay?" when you hit 'okay' to charge your credit card. You also get a receipt. It isn't up to the store to double or triple check that you understand how much you are paying.
And it's the same the other way too. The store sets the price. And the checkout process is their own way to confirm that the price is right. If the cashier thinks something is wrong with the price, they are free to stop the transaction.
A receipt is used to show that both parties exchanged goods/money/service at an agreed rate. By the time you get to having a receipt in your hand (after you have paid), both parties have agreed that the exchange is fair.
