Welcome to Trulia Voices and thank you for your question. Only listings that have been submitted to Trulia manually can be edited at this time. Other listings must be updated with the source that sends your listing information to us. Your listings come to us directly from your MLS and from what I can tell, though they have updated their website with the new price, they have yet to update that price in the data feed they send to us.
I have gone ahead and updated the price for your listing manually and that should update on our site within 24 hours, however I would suggest that you also contact HAR to ensure that they update their feed going forward with the correct pricing information.
Please let us know if you have any additional questions or feedback for us.
