@markcrenz, praktikal, ledrahc thanks for the tip in going to raon. sayang, bibili sana ko mamaya pero baka late na ko makadating don. next time na lang siguro... oh well, antayin ko na lang muna result ng tube shootout kila sir Anthony baka may useful information na makuha dun.
also, to avoid going around in circles. i plan to go straight to a single store since i dont think price will vary greatly. 3800 Php is the going rate, right? which store would you recommend as the most reliable?
