Remember that Ken ships with Purolator, insures the packages, and delivery requires a signature. I don't think Mark insures unless you ask him to and pay for it, he ships with Canada Post I believe, and signatures aren't required unless you request it. So while you're paying less with Mark, there's a better chance that you'll get what Ken ships to you.
Regardless, they both offer a great service, and you can't go wrong regardless of who you deal with. Even in the Classifieds, the guys selling stuff have to get it from somewhere, and unless they've set up their own manufacturing facilities in their basements, I'm assuming that they get what they sell from one or the other more often than not.
As for the original question, he'll get to you when he gets to you; call if you can't wait.
