Uy, totoo yan na may fake S26 Gold sa market kaya dapat talaga mag-ingat! The price difference na nakikita mo, 3000+ versus 3700, usually legit kasi sa authorized retailers ang mas mahal, while smaller sellers or nakalagay na stock nila baka may discount na. But yung mga super mura talaga, like sobrang laki ng gap, red flag na yun for me. One of my mum friends shared na the real thing should have tamang sticker on top ng lid at consistent packaging, kaya always check the details bago bumili, pantayan mo sa authorized stores or trusted pharmacies. I've learned na mas okay bumili sa reliable shops na may warranty rather than save 500-700 pesos tapos baka hindi quality ang formula para sa baby, you know? Worth asking the seller din kung saan nila nakuha supply nila, and honestly, better to pay a bit more for peace of mind! Of course, it's also worth confirming with your pedia kung ano talaga ang best formula for your little one, they'd know what to look out for din.
