Looking for LI 70B Olympus battery in the Philippines?

I experienced more than two times already the camera battery of the Olympus camera gave up on me. I can buy another camera for P5,000 pesos but the battery from

is "only" P650 pesos. I went to the Olympus theme store at SM City 4th floor (near the carpark) and the salesman said that the battery costs a whooping 1, 656.00 pesos #$%!!

It is available at SM department store as the following photo shows:

Perhaps when Olympus cameras will be getting more popular, accessories will become more available and cheaper.
