Vouchers you have claimed may disappear from your My Vouchers page due to these reasons:
To view vouchers that have expired or have been fully redeemed, you can select History > Invalid.
You can also select Get more vouchers from your My Vouchers page to discover new vouchers.
⚠️ Note
Claiming a voucher saves it in your My Vouchers page for easy access, but does not reserve it for your usage. Use vouchers with limited redemptions as soon as possible, to avoid missing out on the voucher's discount.
