Magazine subscriptions also try to bilk you. I get dun letters, some somewhat strongly worded, that I need to pay to renew my subscription. But then I'll look on the cover of the magazine, where my address label is pasted, and it will say my subscription doesn't expire until 10/11 or even 10/12. Why on earth would I want to extend my subscription for a year beyond that??
They are just trying to get your money, and hope you forget you have paid, so next month they can dun you again.
I finally started keeping very good records of each subscription, so I won't be fooled when their renewal notices come around.
The other one I hate is the "automatic renewal" where they renew the subscription whether your want it or not, then send you a notice that you owe them money. Alot of companies have the auto-renew written into the fine print, so you can't avoid agreeing to it.
