Joann's carries them. Just look in the regular quilting fabric area. Usually they are at about eye level running along the fabric display walls (on a little plastic shelf-container thing). You have probably noticed regular fabric fat quarters there. I have purchased some very nice ones, but do check each as some are poor quality, looking faded and thin. They are only $1.99 but go on sale at times for only 99 cents to $1.29 each. Good luck!
