Re: What about advertising
Amazon do love the spam. I'm perfectly happy to take special offers from companies I use a lot. I don't mind a glance at their email, if it's interesting I save for later, or delete if not.
But one day I had 3 different emails from Amazon, and it had got to the point where I was getting more than 10 a week. This didn't make me buy more, it made me hit unsubscribe.
The stupid thing is, they have a good chunk of my purchase history. Some of their stuff seemed well targeted, and so I bought things on special offer I otherwise wouldn't have. But some of the rest of it was horribly badly targeted, and as well as all the attempts at targeted ads, they'd also do general ones for any-old-thing. You'd have thought even marketing could work out that you can have too much of a good thing...
