We pay between $2.75 and $3.50 here at LQS, but sometimes you can get it cheaper on sale. Joanne's has the best price when they are on sale. My LQS sells fabric between $9.50 and $10.95.
I have some Kaffe Facett that is yardage, but I would never pay more than $5 for a fat quarter -- and then only if I needed it for a quilt and I ran out of fabric.
I am on the hunt for a piece of Laurel Burch, but can't see paying what is being asked.
