answer:Years ago my wife and I used to have the Schwann man come by every other week. They sold frozen foods like chicken breasts and steaks and ice cream and such. I suspect you are thinking about something like Peapod, a grocery delivery service. I’ve heard of them and am familiar with them, but have no experience. The Schwann guy keeps track of the stuff you order and always has that on his truck. There is also a catalog of other frozen stuff. It is very like Market Basket which is a fund raiser my son used to sell for his school. Usually the quality is pretty good and portions are good for 2–3 persons per package. I was quite fond of their ice cream treats.
