If it was Progresso soup they have thick cans and ship well when by the case.
Amazon will just throw loose cans of various sizes and weights , even soda pop cans, loose into an oversized box and ship it out, but sometimes when you order cases the package holds together better and will be acceptable by the time it arrives.
The canned soups that arrived OK were 12-packs of Campbell’s. The worst-damaged stuff was an assortment of canned things that my wife had ordered, and Amazon did just what you said, though they did put some brown paper in the box too. The box was damaged, and the cans were all badly dented. I don’t remember how close the food was to its pull date.
