Some attention whoring:
A few days ago, some guy from the Austrian affiliate of GfK (
http://www.gfk.com/at) called me and asked me a few questions about media consumption habits.
In the end, he said that he could send me a link with an online-poll that takes about 30 minutes to complete (for their in-depth analysis).
I accepted, because I'll get a 10€ Amazon coupon.
They sent it today and after filling it out, they sent me the coupon.
(Even I don't really like Amazon, because of their troubles with "slave-work" in Germany recently, it's better than nothing I guess.)
I'll buy the annual yearbook/world almanach called Fischer Weltalmanach with it, when it comes out in September, for 10 instead of 20€:
