It took me a month of fiddling to finally get to the right person within Hawk to be able to use all my certificates on one order. It was kind of a pain in the ass, and honestly, Janet Farwell at SCCA was a pretty good help in getting me in touch with someone who could actually help me. The problem I kept having was when trying to put in several certificates into the web store and having it freak out. The whole thing was a bit of a pain in the ass. Nevermind the fact that I finally got the order placed about six weeks ago, and the it still just says "One or several pieces of your order are on Back Order. It should be ready to ship by November 24th." Now here on December 16th it still says that, and I haven't been able to get much of an answer as to what's going on with it.
Good thing I wasn't in a hurry with all of this, geez. This was my first year dealing with Hawk's contingency, so it was a new experience. (Please Cobalt Friction, please bring back your contingency!)
