Today only, Cheesecake Factory offers two Slice of Joy Cards for free with every $25 Cheesecake Factory Electronic Gift Card purchase. (Each Slice of Joy Card is good for one free slice of cheesecake; they can be redeemed from January 1, 2019, until March 31.) That's tied with last month's mention as the best such deal we've seen from Cheesecake Factory this year.
