Hello P. You already know that it's not the correct price and I would think that the agent corrected the mistake by now, but even if they did not, they still don't have to sell it to you for $41,900. The website is an invitation to make an offer, but it's not an offer to sell at the stated price. Otherwise, you'd just send an acceptance, not an offer. I am sure the Countrywide website also contains a disclaimer concerning accuracy of property information. When you see an advertisement in the paper for a car and the price is wrong, you can't go in the store and demand they sell it to you for that. However, if the mistake is small enough, the merchant may agree to honor the advertised price just to keep the customer happy, not because he/she is legally obligated to sell it for the advertised price. If it's a true mistake, there is no issue with false advertisement either because there was no intention to deceive or mislead.
