US Airways and Frontier airways are selling tickets for $99 each way DFW-RNO. Once you add taxes it isn't too far off from the $200 you want.

Keep in mind that offering cash for a trade will result in a ban as it is against this site's rules. There is also a forum for trades but you don't have access to it yet as you need to wait a certain period of time.

This forum generally is filled with frequent fliers. Requests for "deals" generally are not talked about here because there isn't really such a thing as a deal on an airline ticket. The airlines publish the prices and we are able to buy tickets. The only "trick" IMHO is to know what fares are available and then search until you find seating availability for flights that give you the cheaper price.

On the other hand, if you FIND a deal, feel free to post it in the Mileage Run forum.
