I know what you're saying. There are some things I’ll never order from a place because either it’s too easy and cheap to make at home and/or I can usually make it better than they can – i.e. spag bol or baked salmon. Then there are some things I always leave to the professionals – i.e. sushi, raw oysters and Belgian waffles (I love waffles, but I'm not buying an appliance that makes just one thing that I eat occasionally.)
But I think soups in generally can often be more economical to buy than to make - at least for me. Particularly the labor intensive soups with lots of ingredients and preparation time. Also, and unfortunately, I don’t have lobster or butternut squash or shitake mushrooms in my fridge.
If you have a family making soup makes a lot of sense, but I live alone so 20 servings is a bit much for me. So in my case this works out quite well as I'd rather pay $2.49 for 8 oz of soup than make 8 oz of soup, which is all I really want.
