Schwans has freezer bags. They will leave your food on the back porch and it will stay frozen. But where my wife's step-mother lives in a small Texas town, their Schwans guy has always had a key to their house and put their order in the freezer, and this is going back to at least 1982.
And as a kid (early 1960's) it was always an option to have the milkman let himself in and drop off your order of milk, butter, ice cream and cheese.
It is interesting in this era of Amazon deliver, Uber eats that folks may never ever have to leave their homes again! We've had "Meals on Wheels" non-profit food delivery for shut-ins here for decades for shut-ins, but I am a mobile healthy person, just seems odd to have Taco Bell delivered!
