It was in Chile shediscovered she could get last-minutecheap deals on ships going to Antarctica from the islands off Tierra delFuego, the southernmost tip of the South American mainland.
这是2022年高考考试英语全国甲卷（全国卷Ⅱ）阅读理解C中的一个句子。
请问句中的 last-minute cheap deal 的意思是？
last-minute 的意思是“最后时刻的”，getlast-minute cheap deals on ships 的意思是“买到开船前的便宜船票”（轮船在开船前假如还有没空位的话，此时的票价最非常实惠的）
句意：正是在智利，她发现她可以买到开船前的便宜船票，坐船从南美国内最南端的火地岛附近前往南极洲。
又如下面各句中的 last-minute 均没直译成“最后时刻的”：
a last-minute rush 临时抱佛脚
The prisoner won a last-minute reprieve. 那囚犯在临刑前获得了缓刑。
There was a last-minute rearrangement of theschedule. 程表临到最后还作了重新安排。
They were due to start demolishing the old theatretoday but there’s been a last-minute stay of execution. 原定今天把这座旧戏院拆掉，但临时忽然决定暂缓进行。
