According to the Hungry official website query, red envelopes and vouchers are coupons on the Hungry platform. Red envelopes can be used in combination with vouchers, but attention should be paid to the conditions and restrictions of using red envelopes.

Vouchers generally have certain conditions and restrictions, such as full availability, limited use and single order availability. Therefore, when using vouchers, it is necessary to carefully check the usage rules of vouchers to ensure correct use.
