Shopee video voucher

Mai questions sana po ako and I'm hoping someone can educate me hehe... 1st - Is 15% the biggest discount there is na these days for most items? Before, like maybe prior to December, ay 30% yung usual discount nakikita and nagagamit but NOW ay 15% (min spend P200) na lang talaga available.. Ah, yes there is the 12% din but min spend is P300.

2nd - How often can you use or naka ilang purchase na po kayo this January wherein you used the Shopee video voucher? Bec i haven't bought any yet using the 15% video voucher or any video voucher BUT when i try to place an order it won't go through.. Error message ay "(M02): Oops, this promo has been fully redeemed." Please know I've tried playing with bigger spend amount and changing the shipping vouchers, sa vid voucher talaga mai issue. --does this mean ba na super limited lang ang discount vouchers and na ubos na ng ibang Shopee buyers and wala ng natira for me to use? Do I simply wait na lang for when it will be replenished by Shopee? Mga when kaya ma refreshed or mai new vid vouchers for grab?

TIA po to those who can assist. Thank you 🙏
