Sew News magazine did the same thing to me! I took my sweet time sending it back to them but I also let them know that I didn't appreciate having to return something that I did NOT order!
I think it's a stupid concept to send this out and then expect a return or.. perhaps they hope you won't return it so they can bill you for it.
Nice program they have set up but don't send it unless it's requested, is my thoughts.
Sorry you have to drive to return it, that's not fair!
Just my 2 cents worth
