A grocery-store shopping cart having a main container and an insulated inner container detachably secured within the main container and positioned substantially entirely below the plane of the main-container top edge and adjacent to one endwall thereof to leave substantial storage volume in the main container but outside the inner container, to facilitate diverse-condition grocery cartage. Preferred features include: the inner container being flush with or recessed below the plane to avoid interference during nesting; a hinged cover; and equal acute angles between (1) a main-container endwall and the plane and (2) an inner-container wall and the inner-container top.
