For the post order emails--do they have an 'unsubscribe' button at the bottom of the email?
I signed up for the Passport to Quilting blog, not realizing that it meant I had signed up for the blog of every contributor. I was not at all impressed with the Passport offering and am now in the process of unsubscribing to one or two more a day. I thought I had read all the fine print but guess I missed something. Very annoying.
