Earlier quoted context omitted.
When I was still reading paper magazine, the first thing I did when I received a new issue of The Economist was to shake it over a garbage bin to remove all the inserts and tear up the card board insert in the middle...
Hahah, I did the same. It was either the Economist or FT that did a cost/benefit analysis of removing those inserts for their already-subscribed customers copies, and found that it would cost more in lost new subscriptions to remove them.
How does that make sense?
