Who do you think paid for that stack of catalogs in your mailbox? You did. The companies that send them are smart. If they didn’t have good reason to believe that you would buy plenty of stuff to justify sending you a catalog, then they would stop sending them. I know there are cases where you keep getting a catalog from a company that you rarely buy from, but generally speaking, you are getting those catalogs because you keep paying for them with the products you buy.
I had a normal mail day today with six catalogs in my mailbox. They averaged 100 pages per catalog-that’s 600 pages in a normal day.
