Paddlefish gift cards

[leebee]

Paddlefish is running a cyber-sale: Buy a $50 gift card, get a $15 gift card bonus. Bonus card is only valid for a certain time period but would be valid during our vacation. However... does anyone know if there is a limitation on the number of gift cards that can be applied to one check? The bonus won't have any value for us if we can't use it along with the gift card!
