Trulia provides lots of information for the home buyer. Because the information you are requesting comes from a 3rd party provider, the information is not guaranteed correct and I would bet there is a disclaimer on their website stating this information. Apparently, this home is not being offered at this price, or has not come back on the market from the owner.
Once the property has been assigned to a real estate professional, it will appear in major real estate websites as suggested by Liz, I believe everyone answering your question will have a property search available on their own agent website as well. When looking for properties, those sites with an IDX symbol in searches usually contain the most complete information.
