Short answer — popular places that commonly give free shipping on clothes in the Philippines:

• Shopee (marketplace): free-shipping discount vouchers are issued in-app (often with a minimum spend or during mega sales). Claim them in the Voucher Center / My Vouchers. (productnation.co)
• Lazada (marketplace): runs daily/seasonal free‑shipping promos and voucher events (check the app’s Voucher Center and campaign pages). (lazada.com.ph)
• ZALORA (fashion marketplace): free shipping via minimum‑spend rules, plus a ZALORA VIP subscription that gives unlimited free shipping for a year. (zaloraphilippinesprod.freshdesk.com)
• UNIQLO Philippines (brand site): free standard delivery on online orders above a set minimum (their FAQ shows the current threshold). Click & Collect is also free. (faq-ph.uniqlo.com)
• SHEIN (international fast‑fashion): frequently runs free‑shipping promotions or shows free‑shipping thresholds for the Philippines on its shipping page — check the PH shipping info and promos. (m.shein.com)

Quick practical tips to actually get free shipping

• Always check the Voucher Center / My Vouchers in the app before checkout — free‑shipping vouchers are often limited and time‑bound.
• Combine items from the same seller to meet that seller’s minimum spend (marketplaces usually apply thresholds per seller). (zaloraphilippinesprod.freshdesk.com)
• Shop during mega sales (9.9, 11.11, 12.12, Payday sales) — platforms issue more zero‑minimum or low‑minimum free‑shipping vouchers then. (productnation.co)
• Consider subscription perks (e.g., ZALORA VIP) if you buy clothes often — small yearly fee can pay off with unlimited free delivery. (zalora.com.ph)
• For brand sites (Uniqlo, Bench, Penshoppe, etc.) check their online store FAQ — many have a fixed free‑shipping threshold (or free Click & Collect). (faq-ph.uniqlo.com)
• Watch exclusions: weight/oversized items, certain brands/sellers, or orders shipped from overseas may still incur handling/import fees — always read the shipping terms at checkout. (zaloraphilippinesprod.freshdesk.com)
