Yesterday, I received a magazine through the mail that I'm not interested  
in.  American Family Publishers sent me a letter previously saying that  
I'm "not obligated" to purchase it and offered me "a free opportunity" to  
view the magazine for a certain number of days.  They said that if I'm not  
interested, that I could simply return the magazine and that would be all.   
No bill or nothing.  Now that I'm not interested in this magazine, how  
should I return it.  Conveniently, their is no return address on this type  
of magazine.  Should I just write "return to sender" on the stick-on  
mailing address and assume that the post office will take care of it or  
should I tape on a card (usually included within the magazine with the  
magazine office's address on it) and write "return to sender".  Along the  
terms of the offer, I want to return this magazine and cancel before they  
assume that I want to "accept a membership".  

If anybody knows what I should do, please send me a response...especially  
if you've been in the same situation before.

On a similar, yet different question:  If a company sends you a  
subscription for a magazine/order/whatever and you didn't sign anything,  
are you obligated to pay them?  I'm just curious.
