I just ordered and got the same story. I'm a little annoyed - when I asked for the substitution, the order taker/salesperson said that the kits are prepackaged and they couldn't do it. When I received CMA's "package", they shipped everything except for the wool pad and the white foam pads. So much for prepackaged!
I don't think I'd be as annoyed if they had said: "Sorry, but no substitutions" rather than making up a reason.
(I ordered just after the new year, received the first "package" about a week later (I'm on the westcoast), and the second package with the wool and the foam about a week later.)
