RE #1 & 10
CI is a rather large operation, and generally speaking, when you request a catalog through the website from an operation that size, your info is added to the mailing list, and the next time the updated mailing list is used to address catalogs yours will be in the batch. Due to the long lead times and deadlines, this could actually be one or two catalogs down the line.
I just received a catalog today from a competitor and the addressing was done by printing a sheet of address labels and sticking them on the catalogs. They must be a smaller operation than I had originally thought.
