I have automatic messages from both Hobby Lobby and Jo Ann's (which I signed up for) and they send messages weekly with their ads and sometimes there is free shipping. Plus many of the other quilting on-line sites run specials with either 3.99 or no shipping. Missouri Star Quilt Company has $5.00 flat rate on up to $100 and then it is free as an example.
