I browse around several other web forums, and most of them have a 'free stuff' section. Throughout the years, I've just been receiving a ton of free rpomotional stuff, magazines, being one of the easiest to get.
Just choose a random industry closely related to the magazine (cosmopolitan = textile fab/media/industry/etc) and pick a high ranking officer (I usually pick CFO or CIO). After you're signed up for Mercury mags, they always email free magazines the moment the companies offer them. Stuff from mercury mags ALWAYS come.
Nope, they dont even need a CC number. They do occasionally send renewal letters but just disregard them.
I've been getting free magazines for years and have been giving subscriptions to my family all the time. Magazine companies only get a fraction of earnings in the subscription fee. The most money they make comes from advertising.
More reader base = increased advertising fees
They dont care about your subscription fee, they do care about statistics when they present to advertisers.
Ps, I had a magazine subscription (I think it was PCmag) that runs until 2017.
