Continental Flights from Koror-Yap

I am planning to have a trip from Palau to Yap this X-mas. I checked the price of the flight from Palau to Yap, its like 981US with a stopover in Guam. I am looking for some travel agencies to sell those tickets on a discount. Can someone tell me where I can get a discounted fare? The fare on CO's website is way too sharp. If you have any clue, please let me know. Thanks in advance!!!
