There is, used in most supermarkets (certainly in the Uk in Ireland since the eighties at least) a system of aluminium cages. usually 3 sides to them and wheels like shopping trolleys. The bottom folds up and the sides fold to the back.
picked and filled at the warehouse. dragged onto a truck dragged off at the supermarket emptied on the shop floor. empty trolleys back on the truck. Exceptions seem to be drinks slabs of coke and bottles. which tend to be palletized.
for garden centres there is another system of shelved trolleys for plants often re-shelved for selling direct off the trolley. Plants need to be watered regularly and being mobile is useful.
Clothing often is shipped on racks to avoid creasing too.
pallets are great when shipping 1 product from a factory but not so good for 1 of this 2 of that ect. which is the case often from distribution centres.
