OneTimeCoupon
This plugin provides server administrators with the ability to create and manage single-use coupon codes that players can redeem to receive various rewards or execute special commands. The key feature of the system is that each coupon can only be used once - either by a specific player or by any server member, depending on the administrator's settings.
One-time coupons open up wide possibilities for organizing promotions, rewarding active players, and conducting special events on the server. Administrators can easily configure code usage conditions and automate the reward distribution process.
