Half of my trash is paper catalogs. It's amazing. The decay in the value of catalogs is massive. The response rate for paper catalogs is a giant bell-curve, but massively shifted to the left (if you treat the x-axis as time, moving left to right). The catalog is sent, a ton of orders come in the next week, and then every week the order volume decays rapidly as the prices and merchandise go out of date.
Can't wait until e-commerce supplants paper catalogs completely and I can stop recycling all these dead trees.
