I know this is cheating but: I am so busy right now with work and family I just don't have time to make cutout cookies from scratch.
Do you know of anyplace I can order precut heart shaped frozen sugar cookies?

Not off hand, but you might consider using the Pillsbury (?) sugar cookie dough you can find at the supermarket. You'd still have to cut out your shapes, but at least the dough is ready to go! I don't know how many you would get out of each tube, either.

If you are in Wisconsin, I know that Downtown Dough in Cedarburg has them as does Cake & Bake in Germantown.
