Yardage at my LQS is usually $9.26 and FQ's from the same bolts are $2.90.
But on Mondays, FQ's are 30% off, so they cost $8.12 a yard - less than yardage.
You can also get some fair quality FQ's at Joann Fabrics for $1.00-1.29/each. Sometimes, they have them at 40% off and I've seen them at 2/$1 or 3/$1 for moonlight madness type of sales. Be careful - try to feel a single thickness of each one - hard to do the way they wrap them. Some of them are truly awful fabrics, but a lot them are medium-quality and a few are very nice.
