一周内发货英文

一周之内 within one week (也是正确答案)within a week (是正确答案) 请看例句： The balance will be paid within one week. 余欠之数将於一周内付清. I'd advise booking within a week before. 我建议要在一周之内预定的

就是商家承诺一周内会发货，如果商家没有按照规定时间发货要赔偿违约金

We will be receiving your down payment within one week of the shipment

付款后一周内发货翻译是：Delivery within one week after payment

in a week

within one week h和 within a week 都是可以的。
