The two free slices come in the form of certificates that can be redeemed from 1/1/15 - 3/29/15 (they're good for a slice of cake if cheesecake isn't your thing). Considering that a slice of cheesecake at The Cheesecake Factory goes for at least $6, you're looking at a $12 or so bonus per $25 spent.
The deal is only good on online purchases and only today, Monday, December 1, 2014. You can find the gift cards on The Cheesecake Factory website here.
If you miss out but still want to purchase some Cheesecake Factory gift cards, they're also offering a free slice of cheesecake with every $25 Cheesecake Factory gift card purchase through the end of the year.
