"They do not have high costs."
Translation:Ei nu au costuri mari.
I am romanian and in mu country there is use too the phrase ,,n-au mari costuri " because there is not any difference between those two phrases. Thank you .
"Ei nu au costuri mari." is true for "They do not have BIG costs." "High costs" should be translated "Costuri ridicate". Or... at least both translations should be accepted.
