For more frozen foods I placed an order via
https://www.schwans.com/In my area Schwan's has their own fleet of delivery trucks to deliver to your door sort of like the milkman did in the old days. But they will also ship via UPS.
I thought I'd try them since they have a very good reputation around here. A lot of working folks with long commutes and little time to shop use them. Ordering was easy.
I'm pretty sure their delivery business is way up since the lockdown. I suspect Schwan's parent company is geared mainly towards the B2B trade but they decided to hit the B2C market outside the normal store channels via home delivery which must be successful because they were already operating around here 15 years ago when I moved in and are still going strong.
