Are there any affordable family meal delivery companies?

I'm not going to hold my breath on this, but does anyone know of a decently priced family meal delivery service? One that come in or around a typical monthly grocery budget? I'm in a family of five people, three kids among them. Me and the wife are both working and going to school, so I'm looking for a prepared meal kind of thing that delivers stuff that only requires to be heated up. Most of what I've found via the Internet so far are pretty pricy, as one would expect, but a lot of them are "healthy eating" websites, and I don't really need a particualr carb/calorie diet. I just want to feed my kids at night. Any suggestions?
