As per my observation,
SHOPEE products are cheaper than Lazada for almost 50%.
LAZADA has faster delivery and cheaper shipping fee than Shopee.
Kinumpara ko sila based on the SAME STORE and SAME ITEMS from Shopee and Lazada.
So kung di naman nagmamadali at balak nyo bumili in bulk (should be on the same store) go for Shopee. Pero kung di naman kayo masyado tag tipid at nagmamadali, go for Lazada. ?
