Gandeste-te asa: un carucior este un carucior == un gratar de metal indoit si format astfel incat sa nu-ti cada produsele din el. Caruciorul tau te ajuta sa transporti produse - si poti transporta produsele de oriunde vrei catre orice destinatie (fie ea masina, direct acasa, sau printre rafturile aceluiasi magazin) si pe orice drum (asfaltat, pietruit, prafuit sau cu gropi ).
