I have bought layer cakes, jelly rolls, charms packs etc. Sometimes I save money in the long run by not wasting any fabric. You can make one large quilt out of a layer cake, about $35.00, except for the backing and batting. You can make a simple, fast twin out of a jelly roll. I combined the jelly roll with the layer cake and got two large lap quilts except for backing and borders. So even though they are a lot per yard, I think I save by not over buying fabric. I have enough stash I don't always want to add to it.
