I used to stuff half of my luggage with Filipino groceries before flying back to Singapore. I had no idea that most of the Filipino groceries I wanted were already available at several locations in Singapore. They are up to three times the price but it’s not like I’m able to fly to Manila every other week.
Several grocery store chains in Singapore carry Filipino products. It just takes a bit of patience and searching. Most stores feature them prominently in their international sections, while some you’ll find squeezed between non-Filipino products (like seeing Century Tuna next to Ayam Brand.)
