三个星期左右是 around 3 weeks。in three weeks 是三个星期之后，不是之内。三个星期之内是 within 3 weeks。中国人经常犯这种低级错误。自己有多少水自己先掂量一下，别觉得会骂几句脏话就以为自己是根葱！蠢货！

We can replace them with stainless steel and grey painted cavity for this model as you wish, but then you'll have to pay for additional cost. Besides, we can certainly offer you a sample machine, which will be deliverd in three weeks.
