Forest,
Here are my models

class Style(models.Model):
    name = models.CharField(maxlength=200, core=True)
    image = models.ForeignKey(Photo)
    collection = models.ForeignKey(Collection,
edit_inline=models.TABULAR, num_in_admin=1,
num_extra_on_change=3)
    sandp = models.ManyToManyField(Choice)

class Choice(models.Model):
    choice = models.ForeignKey(Collection,
edit_inline=models.TABULAR,
num_in_admin=5)
    size = models.ForeignKey(Size, core=True)
    price = models.ForeignKey(Price, core=True)
    orderdisplay = models.IntegerField()

class Price(models.Model):
    name = models.DecimalField(max_digits=6,
decimal_places=2)

    def __str__(self,):
        return str(self.name)
