It must be something within what they sent us, or else why would they tell us not to throw anything away, it may or may not be cipher related but it most certainly is related to the envelopes and their contents in some way.
And for all those people who keep saying you can solve this even if you didn't buy, they must be wrong as I have not read that anywhere from CAH only from people in forums and based on the above info we must need what they sent us to solve it therefor we must need to purchase or know someone who did in order to solve it.
