Beware: I recently purchased a Moda Charm Pack (online, through the Fat Quarter Shop) and some of the squares were rather wonky cut and I had to do my best to try to square them up properly. It was disappointing. Luckily, I'm just using the charms to make a cute little baby quilt and I doubt that anyone will ever notice if it is a tad bit "off" here and there. But, after this experience I do not think that I want to trust using pre cuts on any quilt where it really matters.
