便宜一点。

The phrase '便宜一点' (pián yí yī diǎn) literally translates to 'cheaper a bit.' The word '便宜' (pián yí) itself has a history. In classical Chinese, '便' (pián) meant 'convenient' or 'easy,' and '宜' (yí) meant 'suitable' or 'appropriate.' Over time, the combination came to mean 'convenient and suitable,' and eventually, 'inexpensive' or 'cheap.' The addition of '一点' (yī diǎn), meaning 'a little bit,' softens the request and makes it more polite, essentially asking for a slightly more convenient or suitable price.
