Hi Peter,
Anna is correct, you can edit the listing information and change the price from your Listings page (if the listing is not there, you can add it using the search box at the top of the page).
However, f it's being fed to Trulia from the broker website your MLS, or another source, the best way to edit listing information is to change it at the source. This will ensure that the information is congruent, and that if the price is changed in the future, it will automatically syndicate to Trulia.
