Where Can I Buy Lego Bricks Or Anything Similar To Lego Bricks Within Metro Manila In The Philippines?

The cheaper the better. I just need LEGO bricks or any substitute. I don’t need custom characters or vehicles (police, trucks, etc.) Any particular mall or outlet where I can buy LEGO bricks? Please post the mall or outlet, its location, and the item’s estimated price. Thanks a lot.
P.S. Some say Toys R Us or Toy Kingdom would be a good choice but they don’t have a complete list of items. Appreciate it. Thanks.
