You can still find the Ice Cream ones on philosophy.com, when you look for the category, it's called Neapolitan. I don't know where you can still find the Chocolate Chip cookie one. I know Nordstroms also has a big selection of Philosophy.
My favorites are: Cinnamon Buns, Pumpkin Pie, Sugar Plum Fairy (limited edition from Christmas), and Waffle Cone.
