I’ve been subscribing to The Economist for many years; it gives me a good overview of what’s happening in the world (beyond the US), it’s well-written, amusing, and I really enjoy their science and culture sections.
It’s also bloody expensive – $349/year for print and digital (I prefer the print version, though I like having access to their website and podcasts). My subscription was due for renewal on Sunday, and I decided not to renew it. I hoped I could do the deed on the website and not have to talk to anyone.
It was easy – log in, click on “Manage Subscription”, click “Cancel”. Up popped a form asking for my reason to cancel – I clicked the “too expensive” button and was immediately offered one year for half-price.
Naturally, I accepted.

I guess I’m an easy mark sometimes. :-)
