I bought the kit from Amazon 5d Mk3 +24-105. I ordered around the beginning of April they were predicting 6 weeks and I received it around 10 days later. Should say that I'm having fun with it, still learning having come from a 50d. Hope that helps.
Maybe thats why it took longer, changing the model #'s around to D5M3 takes more time, don't u know? Just kidding, OK? Gotta have some fun when you kan. Write?
