Nope, all of it went together. It'll all breakdown and provide nutrients for the soil. And I'm not using them in decorative places so a little big of haphazardness is fine with me.
And yes, it really does come down to the price vs the use. if I was doing a really decorative area I would buy some chip. Though, I might use this as the bottom layer and the nice chip as a top layer to bring down cost.
