Quest Nutrition offers Two QuestBar Protein Bars for free when you like their page on Facebook and fill out a short form. That ties our mention from four weeks ago as the best freebie we've seen from Quest Nutrition. Choose from Chocolate Chip Cookie Dough & White Chocolate Raspberry, Double Chocolate Chunk & Apple Pie, Chocolate Brownie & Cinnamon Roll, and Chocolate Peanut Butter & Coconut Cashew. Expect your bars to arrive in four to eight weeks.
