I recently received a cookbook in the mail that I did not purchase. It was sent to me by a firm I have purchased books from in the past. However, I did not buy this or request it. It was sent through one of those 'try and buy' unsolicited offers.
This is completely anoying because now I have to take the time and expense to return it - or do I?
If it was unsolicited, am I required to return or pay for the item?
I live in Illinois.
