Mailing Frozen or Refrigerated Foods
I've ordered perishable croissants from Williams-Sonoma. They're always packed in a styrofoam container with dry ice, and mailed two-day shipping.
Years ago, I'm talking over 50 years, my mother used to ship hot dogs made in Rochester, NY to my uncle in California. She used to pack the stuff in dry ice, but I have no idea how she sent them, or what condition they were in when they got there. The options for shipping perishables today are far better. Good luck.
I’m interested in the hot dogs your mother sent....I’m always on the look out for really good hotdogs....
