Illuma milk powder Singapore

Agree with what the other mummies have shared! Other than that, one other option you can consider is using Airfrov - it's a platform in Singapore that allows you to get overseas items with the help of travellers who are going/already there. Simply put, you can get Illuma formula from Hong Kong while you're in Singapore - with the help of travellers who happen to be travelling to Hong Kong and get them to buy some back for you with a small fee :)
