I buy most of my precuts from Missouri Star Quilt Co. I have trouble about 50% of the time with them being cut a bit "off". BUT . . . I do not blame MSQC. They are the seller, not the manufacturer. The don't have any control over the quality of these fabrics, they just sell them. So I complain directly to the manufacturer, not the store I purchased them from (though I do let the store know, so they can have a heads up).
As for the value of a precut - they might cost more if you figure it out at a per yard price, but for me, they save me money because I have a habit of over-buying when it comes to yardage. So in the long run, I save money with precuts because I use exactly what is in the pack without all the extra, wasted amount I buy with yardage, but don't actually use.
