Hi! So SpayLater sa Shopee, you basically just select it as your payment option during checkout, it's right there with your other payment methods like credit card or GCash, then Shopee will tell you kung kailan ang due date mo, usually 3 months, at kailangan mo lang i-pay through the app or sa partner banks nila. A few of us moms use it para sa bulk orders ng baby stuff kaya di naman immediately maubos ang budget, hehe!
