20 for each in my case.(used upright piano, local, piano placed on the first floor, very convenient to get in)

You'd better tip extra if your piano is grand or needs to be placed on the 2nd floor.

3个人是不是少了点？钢琴多大啊？我们家两架，搬到二楼的那架是Baby Grand，请专门搬钢琴的公司，这个公司刚开始说3个人肯定够，后来三个人硬是倒腾了近两个小时，连楼梯都没上去。后来说搬不了，就走人了。又请另外一家搬钢琴的公司，来了5个人才弄上去。 我们每人给了$35的小费。
