Agree with Lori S. It's hit or miss.
One thing I like about having a Hobby Lobby close by is that they offer their cotton solids at 30% off every day. I pop in there every so often to purchase a yard or two of white or cream plus one or two other colors to use for pattern testing, learning how to make a block I've never made before, or trying out a new tool or ruler--better than wasting your good fabric.
