FB Workout Programs

Whenever I'm going through all the workout programs Daniel and Kelli have made I always see ones that I really want to purchase. Whether it's FB Flex, FB Abs, FB Blend etc you guys know the programs but then I realize I go through and see I practically want to purchase a whole lot of them. Just out of curiousity, have any of you guys thought of purchasing every single program they have (or just the round ones of each)? Does anyone think it's a good idea to do that at all?
