Gift cards do not have to be ordered in increments of $100 to receive the holiday bonus vouchers. Every $100 worth of gift cards purchased earns a customer a $25 Holiday Bonus card, the gift cards must be purchased at the same time. Meaning, if someone bought two $50 gift cards, but they were separate transactions, they would not be eligible for a Holiday Bonus Voucher.
Example: If you were to purchase one $100 gift card, two $50 gift cards and five $20 gift cards, for a total of $300 worth of gift cards, you would receive three $25 Holiday Bonus Vouchers worth a total of $75.
