We have stacks of plastic tubs around our house:
Note to readers: I may or may not have straightened up before taking the picture on the right. Try not to judge me. Thank you.
Some of the tubs are mailed to Brevig Mission from Anchorage full of groceries. Others come with us as checked baggage when we travel and return full of groceries.
It may sound strange to use plastic tubs as luggage, but in Alaska it's completely normal. Alaska Airlines allows three free checked bags per person when flying within Alaska, and most people take full advantage of that. At the Nome airport I've seen everything from coolers to boxes of diapers come off the baggage carts. The agents don't bat an eye when we check in eight or more tubs in Anchorage.
