Tomato sauce, puree and paste

I have seen tomato puree -- at least in 28 oz. cans -- under the Cento label in our local Kroger; they are next to the crushed tomatoes. (I don't look for crushed or pureed tomatoes in smaller sizes, so I don't know about them.) So it's out there; but maybe not common or easy to find.

Cyndi Johnson Schmitz - I guess you're using different tomato products to get a richer or more balanced taste than just one. Sounds good.
Your idea of using 2 sauce instead of sauce + puree will work.
Other ways to replace the pureed tomatoes -
* buy called passata - an Italian version of pureed tomatoes - may be in the imported or foreign foods section. Probably more expensive than local products, but usually tastes very good.
* buy any format canned tomatoes (whole or diced). Mash up the whole with a fork or potato masher. Or puree either in a blender, processor or bowl with stick blender.
