Jim Cramer says next week, once the Christmas holiday has passed, people are going to be using the gift cards they received -- which should benefit Blackhawk. Cramer calls this gift card provider the most undervalued holiday stock there is right now. He believes it can trade much higher and notes that the company has a lot of new things in its pipeline. Cramer also reveals a couple other stocks he believes investors should put in their stockings. With plans to upgrade their credit card terminals next year, he stresses that VeriFone Systems is extremely undervalued and has a great 2015 ahead of it, while he explains why he is still a fan of Starbucks, which he calls one of the great growth stocks of the moment.
